You recently reviewed an iPad app that lets you use Microsoft Office programs on an iPad. But does this support the “Track Changes” feature of Office, which I cannot find on any of the office-type apps I’ve tried on the iPad?

A:

Yes, it does. And tracked changes are synchronized with your PC or Mac.

As I noted in the review, the new app, called OnLive Desktop, gives you the complete Windows version of Office on an iPad, via the cloud. So all features in the Windows version, including the tracking of changes, are available.

Q:

I am a new Mac user and would like to become a Quicken user. I read your February 2010 critique of Mac Quicken. Is there a new and improved version of Mac Quicken?

A:

Intuit, the maker of the stripped-down Quicken Essentials for Mac I reviewed then, has improved the product. But more important, the company now says its last full version of Quicken for the Mac, called Quicken 2007, will soon be revised so that it runs with Lion, the latest version of the Macintosh operating system.

There was outrage from Mac Quicken users when Intuit earlier had declined to rewrite the full version to work with Lion.

Q:

Could you please tell me which smartphone today is a must if my last phone was the iPhone 4? Your review of the iPhone 4S indicated it wasn’t a “must” upgrade for iPhone 4 owners.

A:

Changing to a different phone would only be a “must” for you if you were unhappy with your iPhone, or wanted one of a couple of key features only available on competing phones.

One would be a larger screen. The iPhone screen is 3.5 inches, but some newer Android phones, such as the Samsung Galaxy Nexus, now have giant screens as large as 4.65 inches. Personally, I find that too large for comfort, but you might not.

Another important feature is LTE wireless capability. A number of Android phones, such as the Motorola Droid RAZR, support LTE, a fourth-generation wireless technology that is much, much faster at data downloads than 3G, though it also tends to use up your battery faster. No iPhone yet supports LTE.

Recent reports have added 4G LTE connectivity and a quad-core processor to a rumored spec list that already includes Siri voice recognition, better cameras, a higher-capacity battery and a much-improved display with double the pixel density of the iPad 2.

All of which sounds entirely reasonable, and certainly like the makings of a formidable successor to the iPad 2. Enough of one that analysts are already tweaking their sales estimates upward.

“We believe this significant refresh will likely help drive higher iPad sales and help further differentiate from arguably the only real competitor in the market, Amazon’s Kindle Fire, and not to mention the myriad of Android offerings out there,” says Sterne Agee analyst Shaw Wu. “We are currently modeling 48 million iPad shipments for calendar 2012.”

That’s an awfully big number, but it could prove too small before the year is out. Says Wu, “[48 million] could turn out conservative.”

Which is why I can’t believe I am missing lovable, furry Grover. The blue Muppet is making an in-the-fur appearance at CES on Tuesday, in a speech by Qualcomm CEO Paul Jacobs, and I am already booked.

The chipmaker has worked with Sesame Workshop on an augmented reality application.

Jacobs is also set to show off other tech stuff, including a demo of Windows 8 running on its hardware and working over AT&T’s LTE network and Lenovo’s Android-based television, which is powered by a Qualcomm chip.

But what has me sore is missing the Muppets. If you are still in Vegas, Grover, call me!

The same folks who were on stage at AT&T’s event this morning — Nokia CEO Stephen Elop, Microsoft CEO Steve Ballmer and AT&T Mobility chief Ralph de la Vega — are all expected here, and one would presume they will have devices in hand.

As a reminder, Nokia has already announced its first Windows Phone for the U.S. — the Lumia 710 for T-Mobile. That phone, due this month, is an entry-level product that will sell for $50 with a new contract.

We’ll have live coverage, wireless permitting, once the event starts around 3 pm PT.

Earlier:

2:53 pm: OK, we’re here, charged up and logged in. Fingers crossed that Wi-Fi behaves for the event, which should run for about an hour.

3:02 pm: Elop takes the stage. “It’s wonderful to be here in North America on behalf of Nokia,” says Elop, the Canadian former Microsoft executive.

3:04 pm: Elop very briefly mentions the company’s entry-level phones for emerging markets, before turning to the company’s Windows Phone-based smartphone strategy.

Elop uses his favorite lines, talking about how a battle of devices is now a war of ecosystems and once again refers to the Lumia 710 and Lumia 800 as the first real Windows Phones.

3:06 pm: Elop talking up Lumia 710, which goes on sale this week (Jan. 11) on T-Mobile.

More war talk: Nokia is establishing beachheads, country by country …

Nokia Lumia 900 for AT&T introduced with a video. Elop holding it up, talking about AT&T’s exclusive.

Initially available in black and cyan (that’s blue to you and me).

Primary camera has Zeiss optics and wide aperture for low light along with a front-facing camera for video chat.

It looks like the Lumia 800, only bigger with its 4.3-inch screen.

3:10 pm: Nokia senior VP Kevin Shields comes up to show off a few of the device’s features.

The device is made from injection-molded polycarbonate, like the N9 and Lumia 800, which it looks an awful lot like.

3:17 pm: Shields touts the phone’s front and rear cameras, Nokia Drive (built-in turn-by-turn directions) and some custom apps such as the ESPN Windows Phone app that is exclusive to Nokia.

Other partners include Univision, the Atlantic Coast Conference and Sesame Street (of which I am a huge fan).

3:21 pm: Ballmer now on stage talking about Microsoft’s partnership with Nokia. He notes that Nokia has delivered the first Windows Phones in well under a year.

3:23 pm: Ballmer underscored, as he has repeatedly of late, that Microsoft has “room to grow” in terms of selling Windows Phones.

3:24 pm: Now out is the third in the executive triumvirate, AT&T Mobility chief Ralph de la Vega. “We’ve been spending a lot of time together,” de la Vega said, noting their appearance together at AT&T’s event this morning.

“Nokia is going to be back in the U.S. in a very big way,” de la Vega said, adding the Lumia 900 will be out “in the coming months.”

“We’re big fans of Windows Phone,” he said.

3:26 pm: Elop isn’t any clearer about Nokia 900 timing, saying only that the device will ship “in the months immediately ahead.”

Time for Q and A.

3:28 pm: What about Verizon? “Today we are just announcing AT&T” but clearly the company wants to get in front of as many U.S. consumers as possible.

3:30 pm: Asked about potential for fragmentation in the Windows Phone market, Elop says he is glad that Nokia isn’t alone in making Windows Phones. “I’m so happy companies like Samsung and HTC are releasing” Windows Phones. “We all need that to get the ecosystem going.”

That said, he added that “we do need some elements of differentiation.” The company is focused on specific apps and other things that won’t break compatibility within Windows Phone.

3:32 pm: Asked about pricing and specifics on availability, Elop again declines to give a more detailed time frame and, on pricing, he says only that it will be “aggressive.”

3:33 pm: As for where Nokia is headed, Elop indicated the company sees room for Windows Phone devices that cost less than the 710.

3:35 pm: In addition to its other app partnerships, Nokia said on Monday that it is working with games leader Electronic Arts to bring more than 20 new games to Windows Phone “coming first to Nokia Lumia devices.”

3:38 pm: Asked about what it would take for Nokia to get into tablets, Elop said it would want room to stand out.

3:40 pm: Why no NFC?

Elop notes that Nokia has been a pioneer in near field communications and already ships it on some Symbian phones.

As for why it is not on the first Windows Phones, Elop said the company had to prioritize and it wasn’t the most critical thing for consumers at this point.

“NFC is growing in importance. It’s something I personally believe in.”

Asked for an update on reports that Nokia looked at some sort of deal for RIM, he said, “There’s never been any information at all so there is no update available.” That said, he indicated Nokia does see an opportunity to make inroads in the business market RIM has dominated.

And with that, the press conference ends.

This year, much of the focus is going to be on the company’s just-launched LTE network and all of the devices that the company plans to have running on it soon.

On Thursday, AT&T announced that it has added service in several more cities, including three of the biggest markets: Los Angeles, New York and the San Francisco Bay Area. In all, the carrier is now in 26 spots, though its network remains far smaller than the LTE footprint of Verizon Wireless.

The company has announced several LTE devices, but a bunch more are expected to be shown later on Monday. The most closely watched of these will be a new Nokia device running Microsoft’s Windows Phone, though we’re also expecting to hear from AT&T about other gadgets, including Samsung’s 5-inch Galaxy Note and Sony’s PlayStation Vita.

AT&T’s act runs from 9 am to 11 am PT. We’ll spare you a full recitation of the script and instead just offer the Playbill summary, along with insight on the performance and maybe a little inside info about the cast.

Earlier:
8:48 am: The good news: AT&T is passing out 5-Hour Energy bottles, more than enough for its keynote. The bad news: No power outlets. Many in the press row are fretting their laptops won’t have enough juice to make it through.

8:50 am: To keep everyone entertained, AT&T has been posting a set of “Would you rather” questions. My favorite one so far was, “Would you rather telecommute using a 14.4Kbps modem or commute two hours each way carpooling with the Kardashians?”

Modem all the way, personally.

Other questions include, “Would you rather use a cellphone from the 1980s or a pager from the 1990s?” and, “Would you rather only be able to text during the day and make calls at night or only be able to make calls during the day and text at night?”

It’s entertaining, but I’m not sure making people choose between two painful options is the branding message you need, AT&T.

8:55 am: OK, we should be getting started in a few minutes. Going to save laptop juice.

By the way, sponsors of AT&T’s developer summit include the expected array of partners — Samsung, HTC, Microsoft — as well as Nokia.

Somehow they managed to get RIM to pay twice, as both QNX and BlackBerry are sponsors.

9:03 am: We must be getting close. AT&T just put a slide on the big screen with its SEC-appeasing “safe harbor” warning. Basically, if things change, you can’t say they didn’t warn you.

9:08 am: AT&T Mobility CEO Ralph de la Vega takes the stage. Overview so far, no news yet.

Expect the new devices toward the end.

9:12 am: Handoff to head marketing guy David Christopher, who is taking a stroll down memory lane, going back 16 years to when the company launched its developer program. I’ll let you know when we get back to the present.

9:13 am: AT&T is announcing a few new programs for developers, including some new programming interfaces to tie into its network.

Lots of carriers are doing this and there are benefits to developers that want to do the extra work. The downside is that developers already have to support multiple operating systems and HTML5. For many, writing to each carrier’s developer tools is too much extra work.

Among the new APIs, though, is carrier billing for payment — that appeals because it helps developers actually get paid.

9:20 am: AT&T is bringing an interesting developer out — Viva Vision chief and former NFL player Joe Tafoya.

Tafoya is showing an app his firm built for Dallas Mavericks player Jason “Jet” Terry. Incidentally, Terry went to high school with our own Tricia Duryee, who is helping out with this live blog, via Webcast.

9:25 am: Some stats on AT&T’s TV product, U-Verse. It’s up to 3.6 million customers, as of last year’s third quarter.

9:31 am: Lots of talk about partners and stuff. Apparently developers have to pay a $99 registration fee and can get unlimited access to the programming interfaces this year.

I’m ready for that energy drink.

Anyway, now up is Chief Technology Officer John Donovan.

He’s talking about the company’s 4G strategy, which includes both its HSPA+ network as well as the LTE network it is just building out now.

“AT&T delivers the best possible blended speed,” Donovan said, noting this is paying off for iPhone 4S users, since that phone supports HSPA+ but not any other 4G network.

He’s talking about the company’s network investments including 80,000 new antennas and 150,000 network improvements.

He’s suggesting the network is going to become like oxygen. Personally, I’m happy that I am able to get oxygen on my own, without having to pay AT&T or rely on them (or anyone else) to deliver it. But that could be just me.

And, as Tricia points out, wireless connectivity is inherently more limited than oxygen molecules, which are abundant, even if increasingly in the shape of carbon dioxide.

9:39 am: AT&T also has a cloud strategy, with droplets and other features that I am a little cloudy on. Got distracted by the clouds on the PowerPoint slide, which look like fluffy little pillows to me.

Donovan promises the ability to pay hourly or monthly for its cloud services and pledges more news on this front this year.

Now he’s talking more about programming interfaces. Developers do care about this stuff, but pretty sure they are all here or watching the Webcast. So I will spare you most of the details.

Donovan said the company expects to see 10 billion calls to its interfaces this year, more than double what it saw in 2011.

9:47 am: Pretty sure we will get some new devices at some point.

But sadly that point is not now.

9:52 am: Promising sign — now up is Senior VP Jeff Bradley who heads AT&T’s device business.

First up, though, are the winners of a developer conference …

Still a bit away from the device news. AT&T is talking about a technology for developers designed to allow their apps to be more power and bandwidth efficient.

10:08 am: Zynga and Pandora talking about how that tech helps their apps be smarter about when and how to connect to the network.

The tool also works across other devices and networks, Zynga noted.

And, Bradley said, it will be made available as open source code later this year.

10:11 am: And, just ahead of the device news, AT&T is talking about AppCenter — its new tool for app discovery. It’s more of a magazine pointing to existing app stores and mobile Web sites than yet another marketplace.

10:12 am: Back on stage are David Christopher and John Donovan. They are talking about three apps created in last night’s hackathon.

It’s similar to what AT&T does at its foundries, but this time live. The winner gets backstage passes to AT&T’s concert with Nickelback as well as the opportunity to be featured in an AT&T ad.

First up is Action X-Ray, which lets you share your extreme sports injuries with friends. It’s really good for targeted ads. Say, if you have a head injury, you get an ad for a helmet.

Next is HopiChest, a health-tracking app for kids to enter stats about their exercise and health habits and tweet it to their friends.

Finally is Sleepbot, which is a mobile and web app designed to help users get a better night’s sleep and compare one’s sleep with others who are tracking their Zzzzzs.

Now the audience is being asked to vote by text message for a winner.

10:19 am: AT&T isn’t the only carrier making news at CES today, by the way. Verizon has just announced the Verizon Jetpack, a new hotspot from ZTE and a new phone from LG.

10:22 am: AT&T is ready to start with its device news as well, with emerging devices head Glenn Lurie on stage. First up is gaming and Sony’s PlayStation Vita.

AT&T has already said it will have the wirelessly connected game console (an announcement made almost a year ago). It will debut next month.

Now it is sharing the fine print.

Sony’s SVP Kuni Suzuki is out, but decides to talk first about Sony’s Tablet P, a dual-screen clamshell device that folds out into a tablet-size screen. Sony announced the device last year and said it would come to AT&T, but again, we’ve been waiting on final details like price and availability.

10:30 am: Now he’s showing off the PS Vita, which is already on sale in Japan, Hong Kong and Taiwan.

He’s showing pictures of the long lines that accompanied the launch. However, after a strong initial burst, sales trailed off.

The Vita is coming to the U.S. on Feb. 22, by the way.

Data plans for the Vita will be similar to the iPad, AT&T announced. For $15 a month, gamers will get 250 MB of data and for $25 a month, they will get 2GB.

However, since the Vita is a designated gaming device, it will be interesting to see if consumers will be willing to pay just as much for wireless connectivity.

The device itself will cost $299.

10:34 am: OK, back to de la Vega for more devices. But first, the results of that developer live pitch. And the winner is…

Action X-Ray, the one that lets you share your injuries with friends.

10:40 am: Device time, starting with six new Android devices, all with LTE.

Sony Xperia Ion, an exclusive to AT&T, will pack a 12 megapixel camera and a 4.6-inch screen. Planned for second quarter (with Sony branding now that it has bought out Ericsson).

Samsung Galaxy S II Skyrocket HD adds a bigger 4.6-inch Super AMOLED screen to the current Skyrocket model as well as a removable battery. Also, as widely leaked, AT&T is getting the Galaxy Note, a 5-inch cross between phone and tablet.

W.P. Hong, Samsung’s head of global product strategy, comes out to explain why we actually need such a thing.

It’s coming to the U.S. exclusively with AT&T and comes in blue and white. U.S. head Kevin Packingham is brought out to add to the Galaxy Note pitch.

He touts the pressure-sensitive pen capability, 5.3-inch screen and other features.

“And yes, it does make phone calls,” Packingham said.

De la Vega says AT&T also wants to bring LTE to the masses and is doing so with a lower-end LTE phone and tablet from Pantech as well as entry-level phone from Samsung.

10:50 am: De la Vega said the Pantech phone will be available for under $50, with a bundle coming that offers the tablet and phone for $249 (as long as you sign up for contracts for both, of course.)

The tablet, the Element, is also waterproof, notes Pantech marketing chief S. Jay Yim, who is now on stage.

Yim ends his talk by dipping the tablet in water, with de la Vega handing him a towel to dry off himself — and the tablet.

The Samsung Exhilarate, an eco-friendly budget LTE phone, will also be priced at less than $50, AT&T said.

10:57 am: OK, Windows Phone time, with de la Vega saying it sees a lot of promise in the platform. AT&T has been the biggest backer of the technology.

AT&T will be first with LTE Windows Phones. And, out comes CEO Steve Ballmer.

“The devices are blindingly fast,” Ballmer said, promising more details will come throughout the day. (Think Nokia event at 3 pm.)

Ballmer draws a contrast between Windows Phone and its app-centric rivals and says that others’ approach puts distance between a user and what they want to do.

“That doesn’t mean we don’t love apps,” Ballmer insists. Microsoft’s approach lets apps work together more easily, he said.

Ballmer notes that the company now has 50,000 apps in its marketplace, with 300 more coming each day.

As for Windows and Windows Phone getting more similar, Ballmer said, “We’ll continue to move in the direction of sharing more technology.”

Ballmer’s also sneaking in a quick pitch for Windows 8.

There have been 3 million downloads of the developer preview version of Windows 8, released at the Build conference last fall, Ballmer said.

Beta coming in February, Ballmer reminds developers.

And, he wraps up with his now-familiar chant of “developers, developers, developers.”

11:08 am: On to Windows Phone devices. Nokia is coming, but first up is HTC.

HTC CEO Peter Chou comes on stage to show that company’s first LTE-capable Windows Phone.

He shows off HTC Titan II, with its whopping 16 megapixel camera.

“I’ve tested it,” Chou said. “It’s blazing fast on the AT&T network.”

The press conference is running over and it’s fingernail biting time in the press row as our laptop batteries all dip into the red.

11:15 am: Chou is cracking up Ballmer and de la Vega. Maybe if he keeps it up there won’t be any time for Nokia.

11:16 am: Nope, here’s Nokia CEO Stephen Elop.

De la Vega said AT&T is betting on Nokia and on Elop. “We have bet on this person because I think he is the right person for this job.”

Elop starts out with his now-familiar line about the battle of devices turning into a war of ecosystems.

He also repeats his assertion that Lumia 710 and Lumia 800 were “the first real Windows Phones,” a phrase that is now doubt giving Chou fits backstage.

Elop promises first 4G LTE phone will be with AT&T.

But he also says that Nokia will share “more details” later this afternoon at its press conference.

And with that, the presentation is over.

The move also will result in four top executives leaving the company, according to a memo from CEO Dan Hesse.

“As the wireless market has evolved, the lines between consumers and businesses have blurred,” Hesse said in the memo, which was first reported by Reuters. “Because of the enormous investments we’re making this year in Network Vision and in the iPhone, we need to consistently be looking for ways to be more efficient.”

Leaving the company are divisional presidents Bob Johnson and Danny Bowman and senior VPs Chris Rogers and John Carney.

All sales will now report to Paget Alves, with all consumer and business marketing being headed by Bill Malloy. Sprint’s machine-to-machine business will switch over to wholesale unit president Matt Carter.

A Sprint representative confirmed the moves and the authenticity of the memo.

Although Sprint got its way in seeing AT&T’s efforts to buy T-Mobile derailed, the company faces plenty of hurdles of its own, and remains a distant No. 3 to AT&T and Verizon Wireless.

The company had placed a big bet on being first to market with a high-speed 4G network, choosing WiMax. However, with LTE offering higher speeds and more ubiquitous adoption, the carrier is now shifting gears and aiming to build an LTE network, as well.

Sprint said this week that it will launch by midyear in several southern U.S. cities, but it now trails both AT&T and Verizon in the LTE race.

Also, as paidContent’s Tom Krazit notes, the Sprint Web site could do with a bit of business/consumer consolidation, too. The screenshot below is what folks see when going to Sprint.com:

Updated at 1:40 pm PT to include confirmation of the moves by a Sprint representative.

On the intended front, CEO Dan Hesse told investors that the company would launch its first high-speed LTE service before the middle of the year in Atlanta, Dallas, Houston and San Antonio.

Perhaps less intended was the announcement of the company’s first LTE smartphone. However, as spotted by The Verge, Sprint is advertising on CNET’s CES page that the Samsung Galaxy Nexus will be the company’s first LTE phone. Clicking on the phone in the ad does nothing, while a link in the bottom of the ad for more info about Sprint’s LTE plans led to an error page as of Thursday afternoon.

After being early to the game with its WiMax-based 4G network, Sprint is now racing to catch up as it adopts LTE. Verizon already has coverage in a good chunk of the nation, while AT&T announced on Thursday that it is offering service in 11 more cities, including Los Angeles, the New York City Metro area and the San Francisco Bay Area.

I’ve asked the company for more details on its plans for the Galaxy Nexus and whether the ad was meant to go live on Thursday.

Update, 5:50 p.m. PT: In a story on its own site, CNET said the ad was published accidentally.

Also getting the service are Austin; Chapel Hill, N.C.; Orlando; Phoenix; Raleigh, N.C.; and San Diego, Calif.

That’s in addition to the 15 other markets in which AT&T launched LTE last year. Of course, AT&T still trails Verizon, which has coverage in 190 markets, with service available to more than 200 million people.

Sprint, meanwhile, has much of the country covered with an alternate 4G technology, WiMax. However, Sprint has announced plans to launch an LTE network of its own later this year.

Constrained by spectrum, T-Mobile USA has focused on rolling out ever-faster variants of its 3G network. The company had hoped a merger with AT&T would solve its problems, but is now scrambling for other options since that deal collapsed.

Update, 1 p.m.: In a Twitter posting, Sprint noted on Wednesday that it plans to launch its LTE service in Atlanta, Dallas, Houston and San Antonio by mid-year.

Responding to a Boy Genius Report post claiming it hasn’t yet been able to integrate its core email, calendar and messenger features into BlackBerry 10, RIM said the post was “inaccurate and uninformed,” and reiterated its original explanation for delaying the first phones running its next-generation platform until the latter half of 2012: The company is waiting on a more power-efficient LTE chipset.

“RIM made a strategic decision to launch BlackBerry 10 devices with a new, LTE-based dual core chip set architecture,” the company said in a statement given to AllThingsD. “As explained on our earnings call, the broad engineering impact of this decision and certain other factors significantly influenced the anticipated timing for the BlackBerry 10 devices. The anonymous claim suggesting otherwise is inaccurate and uninformed. As RIM has previously explained, and as Mike Lazaridis reiterated on the earnings call, we will not launch BlackBerry 10 devices until we know they are ready and we believe this new chip set architecture is required to deliver the world class user experience that our customers will expect. Any suggestion to the contrary is simply false.”

So … whom to believe? That’s a tough call at this point, given RIM’s narrative over the past year. As one source close to the company told me, “I don’t know if the BGR report is true, but it’s certainly plausible. RIM’s a train wreck right now and the ‘we’re waiting for an LTE’ excuse rings a bit hollow to me.” Whatever the case, it’s easy to believe the worst, and that’s sadly telling in itself.
