But fortunately, there are a few free tax apps that can help you with that paperwork.*

Before you get started, you might want to use a tax calculator to estimate how much you’ll get in returns … or how much you’ll owe. The TurboTax TaxCaster is scientifically unproven to either make you shout aloud with joy in the middle of the office or cause your stomach to drop faster than if you were riding this. The TaxCaster app is free on iOS and Android mobile devices as well as online.

TurboTax's iPad app

For preparing your tax paperwork, there’s now a TurboTax iPad app. Intuit actually launched the app last March, but it was too late in the season to really gain traction. The iPad app works even when you’re offline, so you can prepare your tax paperwork from almost anywhere.

This year, TurboTax, which says more than 70 percent of its customers now file online, has added some new features to the iPad app. First, it has hired 700 CPAs and tax attorneys nationwide to be on call for questions that app users might have.

Also, filers can now import data and forms from about 400,000 employers and financial institutions.

Lastly, the app’s keypad has a new user-friendly design. The large, optimized keypad is a good idea. Even when your eyes start to glaze over, you can’t miss the keys.

As with the rest of TurboTax’s mobile apps, it won’t cost users anything to download the iPad app and punch in their information, but users will be charged through iTunes when they go to actually e-file through TurboTax. At the low end, TurboTax Deluxe costs $29.99.

H&R Block has introduced a new mobile app for iPhone and Android devices that allows filers to complete a federal 1040EZ form and state return by snapping a photo of their W-2 forms (TurboTax’s SnapTax does this as well.) The service is free through February 29th.

Filers with more complex tax returns can use the H&R Block iPad app to complete those additional forms.

H&R Block’s smartphone app also aims to help users locate a nearby H&R Block office, estimate a tax refund, check the status on a refund, and decipher various tax terms with a glossary.

Like TurboTax, H&R Block is now offering free extended support for taxpayers, through a Tax Answers program. And if you’d rather have your tax returns filed for you through video conferencing, H&R does that, too, through its new Block Live service.

Keep in mind that if your gross adjusted income last year was $57,000 or less, you can qualify for free e-filing through the IRS’s Web site. And as Ina Fried pointed out a year ago at this time, the IRS has a mobile app for iPhone and Android phones that lets users track their refund status.

*This is the sentence in which I feign enthusiasm over tax season.

Seattle-based Treemo Labs has created an iOS app maker called Appafolio that requires no code in the app-building process, will show up to 10 screens of data or imagery, and caches the app content so the app will work even when an Internet connection isn’t available.

The company wants to become an app resource for business users and marketing professionals who want to create brochure-like apps that likely won’t pass muster in the App Store. Appafolio is free, though there will be a premium model that offers more bells and whistles.

There’s also a simple Appafolio pass phrase that app makers can use as a URL and share with anybody, directing iPhone and iPad users directly to their app instead of to an app store or marketplace. The link won’t, however, work on a Web browser.

Treemo co-founder and CEO Brent Brookler pointed to camera company Contour as an example. Contour used Appafolio to show off its new line of cameras a few weeks ago at the Consumer Electronics Show — where the cellular service and Wi-Fi connectivity is notoriously bad. The company used an iPad as a kind of marketing brochure at its booth, and since the content of the app could be downloaded and cached in advance, there were no issues swiping through the Contour app and viewing all of the data available.

Of course, the number of companies that help people make apps is as large as the day is long — and some them also offer no-code builds. There’s also AppMkr, AppIncubator, AppWhirl from App.co, AppVoyage and EachScape, which just nabbed $3 million in Series A funding, to name just a handful.

While the Appafolio product is geared toward business clients, the app maker doesn’t allow users to import things like PDF or PowerPoint files. So, for an offline deck, the non-iPad-owning business user might still turn to other software applications to create slides or brochures.

And while Brookler sees getting an Android app going as an important step to market Appafolio to the masses, for now the app is iOS-only.

Brookler says the app isn’t just for business users; a casual user might want to create an app for a wedding, for example. But that sort of app is also unlikely to pass App Store muster, so Appafolio makes it easier for those users to become developers for a day.

Seattle-based Treemo Labs launched in 2005 and has mainly created apps for media properties, including CBS News, “60 Minutes” and “Survivor,” as well as music video apps.

As of today, Pulse users can subscribe to a curated feed of trending election news, or follow dedicated feeds around specific candidates or political commentators. (So I suppose you don’t really have to leave the comfortable confines of the filter bubble, if you don’t want to.)

Pulse is available for iPad, iPhone, Android and Windows Phone. It adds 1.5 million to two million new users per month, according to CEO Akshay Kothari. He said those users read more than five million stories per day. Kothari declined to comment on plans to add a desktop version.

Via Kothari, here are the new Pulse news sources: Fox News, the New Republic, the Los Angeles Times, Talking Points Memo, Daily Kos and Reason Magazine; plus dedicated political news from previous sources the Daily Beast, the Atlantic, the Atlantic Wire, Slate, Al Jazeera, the New Yorker, USA Today and the Huffington Post.

Included presidential candidates are Barack Obama, Mitt Romney, Newt Gingrich, Ron Paul and Rick Santorum.

And included political commentators are Rachel Maddow, Hendrik Hertzberg, Erick Erickson, John Cassidy, David Brody, Jared Bernstein and David Horsey.

Remarking on sales of the 4S in Greater China, during the company’s recent first-quarter earnings call, CEO Tim Cook said demand for the device there has been staggering. “We felt we were betting bold, as I think many of you would have thought if you would have known what we were doing,” Cook said of the 4S rollout plan for the country. “But as it turns out, we didn’t bet high enough.”

That’s a rare admission of misjudgment from a company that doesn’t often make them. It’s also a comment that speaks to the massive size of the Chinese market, which remains largely untapped by Apple, thanks to its lone-carrier deal in the country.

Right now, Apple only has a deal with China Unicom, which gives it access to about 10 percent of China’s 150 million “high-end” mobile subscribers, according to Morgan Stanley analyst Katy Huberty. If it were to a sign a similar deal with China Telecom, it would gain access to another 15 million. And if it at long last brought the iPhone to China Mobile, it would gain access to an additional 120 million.

That’s a massive addressable market, and one that Apple can ill afford to ignore. To do so would be to leave a lot of easy money on the table, according to Huberty. She figures that adding China Telecom as a carrier partner would create an additional two million to four million iPhone users in the near term. And adding China Mobile would create a much bigger multiple of that.

“We estimate China Unicom has 3 million iPhone users, implying a 20 percent penetration of its 15 million high-end subscriber base,” Huberty said. “The same penetration at China Mobile given its 120 million high-end subscribers would equate to 24 million iPhones, with 14 million switching from other feature phones or smartphones and 10 million existing iPhone users on the 2G network upgrading to the faster 4G network.”

Huberty expects the iPhone to arrive on China Telecom in the next few months. Its debut on China Mobile, however, will take a bit longer, and isn’t likely to occur until Apple introduces the iPhone 5, which is expected to be compatible with the carrier’s upcoming 4G network (TD-LTE).

So, 24 million to 26 million additional iPhone users, if Apple were to sign up both China Telecom and China Mobile. And that’s the base-case scenario. Huberty’s more bullish view of the situation lifts that number to 40 million, and predicts that a few years from now, Apple could sell 57 million iPhones per year in China alone. And that is truly a spectacular number.

After all, Apple sold 68.5 million iPhones worldwide in fiscal 2011.

A start-up called Tilera today unveiled a chip it calls the TILE-Gx. Essentially, it’s a super-chip with 36 cores which — so the company claims — beats a traditional Intel server chip on the key metric of performance per watt.

For those who don’t keep score in the arcane world of semiconductors, I’ll revisit some of the basics of the above paragraph. We all know that Intel and its one main rival, Advanced Micro Devices, sell chips for servers. Those chips, and those that go into PCs, are generally known as x86 chips, a name derived from the instruction set they share.

On the other hand, there are ARM chips, which are a different breed, and exist in a very different ecosystem. Scores of companies make ARM-based chips for all kinds of different uses, and they license the basics of the designs from ARM, the company, which last year did $636 million in revenue.

ARM chips show up in phones and tablets from the likes of Broadcom, Qualcomm, Texas Instruments and Nvidia, but not so much in PCs and servers. ARM is even the basis for Apple’s A4 and A5 chips. At CES last year, Microsoft said it would create a version of Windows 8 that will support ARM chips. And a company called Calxeda (which I initially got mixed up with Tilera) is aiming to bring ARM cores to chips running in servers.

Tilera, based in San Jose, Calif., is backed by investments from Bessemer Venture Partners, Walden International, Columbia Capital and VentureTech Alliance; plus a trio of strategic investors, Quanta Computer, NTT Finance and Broadcom. Its new chip is based around an entirely new architecture developed by Tilera’s CTO Anant Agarwal, a professor at the Massachusetts Institute of Technology. It forgoes both the traditional x86 and ARM architectures. Aimed squarely at servers, its intention is to get the same work done that a traditional Intel server chip does, while using less power to do it.

That’s not a trivial benefit, especially in data center environments where servers are bunched together and pushed to the performance limit. The biggest operational expense in running them is going to be power. So it’s on this point that server vendors and chip vendors obsess over saving a watt here and there — over the machine’s useful lifetime, the costs will add up considerably.

How it does this is what makes it interesting. Essentially, the cores on the chip do something that an Intel chip can’t do: They communicate among themselves. The way I understand it — and I admit I’m simplifying it greatly — the cores on an x86 chip rely on a single communications channel, called the Bus, to communicate. The Tilera architecture allows each core to communicate directly with the other cores, thus eliminating the need for the Bus and cutting back on the need for power.

The top-end chip — there are two versions — has 36 cores. A core is essentially the main computing engine on a chip. If you’re reading this on a PC, chances are the chip inside it has two cores, maybe four. It used to be that chips had only one core, until it became logical to put two or more on a single chip. I’ve always compared multicore chips to roommates folding laundry together. When there’s a big pile of laundry to be folded, one person can certainly do it, but two or four get it done faster and with less effort. Multicore chips basically prove the old adage that many hands make for fast work.

There’s an obvious appeal to a chip like this, but there are a lot of strikes against it. First, much of the server ecosystem is pretty well entrenched. Companies run what applications they already have, and are usually loath to mess with their computing environments much. Changing the architecture of the CPU chip inside the servers is about as major a decision as a CIO may ever make, and one they don’t make lightly. First they’ll have to test it and run it for awhile, and then see how it interacts with other systems. It’s not the sort of decision that happens just overnight. Also, a new architecture brings with it a lot of software compatibility questions that will give many IT departments pause.

Meanwhile, Intel, which sells chips that go into most of the world’s mainstream servers, will continue to push its power consumption down. At the same time, it’s been trying like crazy to use its Atom line of chips to mount an attack on ARM’s territory and win business from phone and tablet vendors. That effort is just now seeing its first early successes. If there’s a great long-term story in chips that bears watching, the grappling between Intel and the ever-expanding universe of ARM vendors is certainly it.

Correction: I initially thought the Tilera chip was based on the ARM architecture. I’ve revised the story to correct that.

“We run the iPhone and iPad teams separately from the Web team, and the Web team had fallen behind,” said Paul English, co-founder and CTO.

The goal with the site’s design has always been to provide a simple layout, so that users can easily sift through thousands of flights, hotels and car rentals to find what they are looking for quickly.

But up until now, the focus wasn’t really on being beautiful, English said. The new look tries to incorporate a clean and attractive design.

After eight years in business, English said this is the most significant redesign of the site (check out the gallery below to see how the site has changed over the years). But only the most die-hard users are likely to notice many differences. Rather, the larger significance is that mobile is influencing the Web, and not the other way around.

Increasingly, this may be the case in the travel industry as so much of the traffic now comes from phones and tablets. Kayak said more than five million applications were downloaded in the nine months ended in September, a 97 percent increase over the same period a year earlier.

In early testing, English said conversion rates are higher and completion times are shorter as a result of incorporating mobile designs — which, by nature, are always built with speed and ease-of-use in mind. “They [customers] are more confident to compete the purchase because we haven’t worn them out.”

Here’s some of the more notable changes:

The unibrow is gone: Internally, the company refers to “the unibrow” as the black bar that stretched across the the top of the page that said “Search One and Done.” Now at the top of the screen are several tabs, such as Flights, Hotels, Cars, etc.

Similar to iOS: The iPhone and iPad designers released a new iPad app about a month ago. In the new Web site design, they leaned on the design to bring a consistent typeface and coloring to the Web site.

Fewer ads on the site: When users are looking at photos of a hotel or viewing a map, they won’t see any ads. “Obviously, ads are an important part of the way we make money, but advertisers have gotten clever, and sometimes the ad is jarring and has animation,” English said. Kayak is issuing all-new guidelines that requires advertisements to blend with the site. “If you do a good job, it should be content. If we are showing you ads that are extremely related to what you are doing, it’s useful.”

Most of the changes will go live today, with some of the others — like the new ad guidelines — taking more time to implement.

English declined to provide an update on the company’s IPO. While it continues to file financial updates with the Securities and Exchange Commission, Kayak told AllThingsD in September that it was putting its plans on hold.

The piece elicited a variety of reactions — even Roger Ebert seems to think it might be too late to learn a new keyboard. I also received a fair number of follow-up emails pointing out some interesting technologies that I’d missed.

So here are some other options for the touchscreen-averse:

Talk Emo to Me

A company called Siine is trying make touchscreen typing even quicker by replacing words or entire phrases with emoticons.

The Siine Writer app is based on editable icons. Each icon, or “Siine,” is supposed to convey three different words or phrases, depending on how many times the user taps it.

So, instead of typing out a text-laden message, users tap a series of visual cues that send the message to the person on the receiving end.

Users make the Siines by downloading the app from the Android market, going to the emoticon screen, holding down an emoticon and selecting “create,” to assign a new picture, a name and the corresponding text for the emoticon. After that, the Siine emoticon will appear on the user’s keyboard.

It’s a pretty nifty idea, though there would likely still be a need to enter text for more random words, and words used less frequently.

Siine is based in London and Barcelona; the company launched in 2007, and received funding last February from Atomico, the VC firm of Niklas Zennstrom, best known for co-founding Skype.

The free app is available in both English and Spanish for devices running Android OS. There’s also a tablet version of the app, available exclusively from Samsung Apps; at the moment, there isn’t a Siine app available for iPhone or iPad.

The Next Productivity Killer at Work

Here’s a familiar sequence of events: You’re typing away at your desk, and your phone pings — loudly — alerting you and the rest of the office to the fact that you’ve got a message. You’re in the middle of doing work, so you ignore it. But you don’t, really: You glance at your phone’s interface, quickly, just to check. But, wait — it’s your friend, asking if you want in on tickets that are going to sell out in exactly 47 seconds. Or it’s your significant other, asking if you could meet the handyman at the apartment. Or it’s your mom. You simply have to respond.

What if you could just keep typing on your desktop keyboard — and still respond to your urgent calls?

That’s the kind of keyboard Matias has come up with.

The Canada-based company uses Bluetooth technology to wirelessly connect your phone to your keyboard and toggle between your desktop screen and phone — you’re still typing on your keyboard, but the text is appearing on the screen of your smartphone. (Here’s a video from CES that shows how this works, courtesy of Engadget.)

There are three Matias models — the $79 Slim One Keyboard, the $99 One Keyboard and the $199 Tactile One Keyboard — and all of them work on both PCs and Macs. The One and the Slim One are available now; the Tactile One will begin shipping in May.

The cheapest model, the Slim One, does not include a hub for your phone. The $99 One Keyboard includes a USB 2.0 hub and in-keyboard stand to hold your phone. The $199 Tactile One Keyboard has all of that, plus Alps mechanical key switches, which means there are real switches under each key.

And for those of you who wrote to me and suggested the Dvorak style of keyboard as an alternative to the traditional keyboard layout — Matias also makes a Dvorak keyboard for PCs and Mac computers.

Projecting Into the Future

We’ve seen at least one example of a laser-projection device that can create a keyboard out of any opaque surface. But what if you could make a keyboard out of any surface? What if you could make a keyboard … out of thin air?

MicroVision, a company specializing in laser-display technology, announced earlier this month the availability of its new laser-display engine, the PicoP Gen 2 HD laser display (the company’s patented display, PicoP, is actually the tech behind OmniTouch, mentioned in the previous article.)

The Gen 2 display takes it a step further: MicroVision’s PicoP Gen 2 can turn any projected image into a virtual touchscreen, regardless of the surface it’s being projected onto — or whether there’s even any surface at all. The PicoP Gen 2 HD laser display engine boasts 720p HD image projection and interactive displays up to 200 inches diagonal. MicroVision also announced technology for 3-D projectors, which could project 3-D images from a small display device.

While this kind of technology might have a more obvious place in the gaming market, it can also be used in conjunction with mobile devices to allow users to “step away from the screen.”

The company is emphasizing that this is still a prototype; MicroVision expects to begin sending samples to selected manufacturers for testing sometime early this year.

(There aren’t any images of this technology being deployed, so you’ll just have to imagine that keyboard in thin air for now.)

Forget the Keyboard — It’s All About Voice

Still other readers threw the four-letter word at me. Not that one. They were talking about Siri — and her competitors — saying they believe that touchscreen technologies, tactile or otherwise, are all moot because of the emergence of voice-command technology. Voice recognition is now in smartphones, gaming consoles and “smart” TV sets; is it only a matter of time before we’re dictating everything to our computer screens?

This year, even the big case makers took a pass on the show.

Although attendance is projected to be up slightly, to 25,000 people, the show floor didn’t reflect the surge of popularity around Apple’s products — a surge that has led to a significant rise in Apple gear at the Consumer Electronics Show. Macworld organizer IDG World Expo wouldn’t say how much square footage it had sold this year, saying only that there were about 300 exhibitors.

The biggest name on the floor was Hewlett-Packard, whose large booth was at the entrance to the exhibit hall at Moscone West in San Francisco.

From there, the big names were few and far between. Of course, Apple wasn’t there. Nor was Adobe, or Microsoft. Also missing were big accessory makers like Belkin, Speck and Griffin.

In their place was an odd collection of start-ups looking for attention.

Several of the booths showcased former Kickstarter projects hoping for new business partners. Olloclip was there, pitching their add-on iPhone lenses, while iKeyboard was there to show a physical keyboard that attaches to the face of the iPad to give the touchscreen a tactile response. Another booth was pitching an interesting docking station called LandingZone, designed specifically for the MacBook Air.

There were still lots of iPhone and iPad cases, of course, even if fewer than at CES or Macworlds of years past. One interesting product line featured eco-friendly, made-in-the-U.S. phone cases that are also compostable, for when Apple comes out with a new model and you need to switch.

One of the other vendors that caught my eye was VanGogh Imaging, which was using four Kinect sensors to capture 3-D images and create a visual model. While creating a virtual Mini-Me, company CEO Ken Lee explained how VanGogh hopes that cellphones and tablets can be used to capture, render and display the models.

“We’re here to look for partners,” Lee said.

But my favorite was the booth for a gadget insurer called Worth Ave. Group. The company had created a cellphone twist on the classic Whac-A-Mole arcade game, allowing convention-goers an opportunity to pound out their smartphone frustrations.
