The iPad 2 Is No Retina Display, but Still Easy on the Eyes

Ina Fried — Thu, 17 Mar 2011 21:30:00 +0000

Although some Apple enthusiasts were hoping the company might have some super-duper-mega-retina display on the new iPad, the tablet does have a pretty darn good screen, says one analyst who has taken a close look at the iPad 2.

In a blog post, DisplayMate President Ray Soneira said the iPad 2 screen may not pack as many pixels per inch as the iPhone 4′s Retina Display, but the screen offers similar high performance.

“What has amazed and impressed me about the iPad 2 is that Apple has included a first rate (screen) at a very aggressive price point and not used a cheaper second or third tier LCD, which is what most manufacturers do under these circumstances,” Soneira said.

While the display and performance have gotten reasonably high marks, analysts and reviewers have noted Apple chose to include rather weak cameras in the device.

The display on new iPad offers 132 pixels per inch as compared to the 326 ppi offered by the iPhone 4. However, its total screen resolution is still higher owing to its significantly larger size.

Despite the overall praise, Soneira did find a couple bones to pick with Apple’s displays. First, he said that the way Apple handles reducing jaggies, known as anti-aliasing, reduces how sharp graphics and text appears on the screen. The approach, he said, is far from state-of-the-art when compared to technologies such as Microsoft’s ClearType.

Also, he said, the company’s approach to auto-brightness is also less sophisticated than it should be, impacting both eye strain and battery life.

However, both issues could be addressed through a software update, he said.

“This is all done in the iOS software, so Apple could (or rather should) fix Auto Brightness for all iOS devices,” he said.

Blogs, MacBooks and GSM phones

Walter S. Mossberg — Wed, 16 Feb 2011 23:20:02 +0000

I’ll be starting a two-year assignment with the Peace Corps in the near future. I would like to start a blog where I can record my daily activities for my friends and family to read. Do you have any suggestions?

There are numerous free blogging services that offer templates, simple tools and a free address your friends and family can use to view your reports. Two that I have used and can suggest are Blogger, owned by Google, at blogger.com; and the independent WordPress, at wordpress.com.

In terms of battery life, does it make any practical difference if I leave my common programs on my MacBook Pro running when dormant versus shutting them down when I’m not using them and then firing them up as needed?

I asked Apple about this, and the company said an open, but idle, application on a Mac notebook generally won’t use any or many processor resources, which means almost no impact on battery life, even if it performs periodic background actions like fetching mail.

Exceptions would be programs that do heavy-duty things in the background, like rendering videos. The company strongly advises making sure the laptop is in sleep mode when not in use, and keeping the screen at the lowest brightness level that works for you.

Also, you can check how much demand a program is placing on the processor by running the Activity Monitor, located in the Utilities folder in Applications.

Why would a GSM phone run in 3G-mode only on AT&T and not on T-Mobile?

It’s true that both carriers use the same basic technology, called GSM. But, in some cases, phones (like the AT&T iPhone) are locked so that, unless you do serious hacking, you can use them on only one of the two networks.

In other cases, it might have to do with the frequencies used by a carrier. T-Mobile and AT&T use different frequencies for their 3G networks, and a phone might simply be built to support only the 3G frequencies used by one of the carriers and not the other.

New Mac Laptops Use Batteries Sealed for Power

Walter S. Mossberg — Thu, 25 Jun 2009 01:04:03 +0000

The majority of laptop computers come with removable batteries. This approach allows you to pop in a fresh spare when your battery runs out of juice between charges, and to easily replace a battery when its lifespan is over.

But there’s a dirty little secret about removable-battery laptops owned by average consumers: Hardly anybody buys extra batteries. Research firm NPD estimates that fewer than 5% of consumers buy a spare. So, a small trend has begun in the industry: More electronic products are being designed with their rechargeable batteries sealed inside. For instance, Dell’s (DELL) new high-end laptop, the Adamo, has a sealed battery, as does the excellent Flip pocket video camera.

[ See post to watch video ]

The leading proponent of this idea is Apple (AAPL), which has often led the industry in introducing or removing components from computers. This month, Apple unveiled two revised MacBook Pro laptops with higher-capacity, sealed-in batteries. In fact, Apple’s entire line of laptops now uses sealed batteries, except for one low-end MacBook model from last year’s series.

Apple says this makes sense because sealing in the batteries lets the company make them larger, without adding heft to the laptops. Apple says the two models are the same size and weight as their predecessors, yet their battery capacity has grown by 33% and 46%, respectively.

And, Apple asserts, it has come up with some software technology that allows these sealed batteries to last up to five years in typical use. The company claims that is almost triple the industry average for removable batteries and is longer than the typical time consumers keep the computer, thus making it far less likely you’ll need to replace a dead battery. Apple says it is able to seal in bigger batteries without making the machines larger because the company can compensate by shedding the casings, internal housings and other components needed by replaceable power packs.

The 13-inch MacBook Pro

I’ve been testing these two new Apple laptops, the 13-inch MacBook Pro and the 15-inch MacBook Pro, using my own harsh battery test, which I apply to all laptops I review. The results were excellent. These two new Apple laptops scored among the highest battery lives between charges of any laptop I have ever tested with a battery that fits entirely inside the machine’s dimensions, without sticking out of the back or bottom and adding weight.

The smaller of the two machines lasted a few minutes shy of five hours in my test. And the larger one lasted five hours and 21 minutes. I estimate that, in a more normal usage scenario, both machines would come close to Apple’s claim of around seven hours between charges—essentially a full workday of unplugged use. Those numbers are likely to obviate the need for spare batteries for the majority of average consumers.

There are some important caveats. I was unable to verify Apple’s claim that these sealed batteries can be fully recharged up to 1,000 times, and thus, last around five years. Second, if and when the sealed batteries do become unable to hold an adequate charge, the entire computer must be returned to Apple for a new battery. The company says that, if you do this at an Apple store, it’s a same-day process and, at least on the 13-inch model, the price of a new battery is the same as what Apple formerly charged for a new removable battery. But it’s still more of a hassle.

Also, there are users—like people who work on very long flights—for whom replaceable batteries will always be a necessity. These users will want the option, unavailable on the new Macs, to pop in an extra-strength battery.

Finally, while Apple has cut the prices of these two new laptops, they are still pricey compared with similar-sized models from other companies. The 13-inch model starts at $1,199, and the 15-inch model starts at $1,699. Like all Macs, these computers have, in my opinion, a better operating system, better built-in software and better security than their Windows competitors. But you can get competing machines for hundreds of dollars less.

In my battery test, I turn off all power-saving features, leave the Wi-Fi network on, crank up the screen to 100% brightness, and play a continuous loop of music. That maximizes some of the biggest power hogs on a laptop. In normal use, a typical owner would likely use the power-saving features, turn the screen down a bit, have Wi-Fi off some of the time, and wouldn’t be running the hard disk constantly.

Neither of my test machines used the energy-saving, but costly, solid-state drives that are slowly replacing mechanical hard disks. And my test models both used integrated graphics chips, which suck less power than the more potent discrete graphics offered on the 15-inch model.

Still, I believe that these new MacBook Pros prove that sealed batteries can result in a very good experience for average users.

Two New Devices Give Presentations Some Portability

Nick Wingfield — Thu, 11 Dec 2008 02:08:05 +0000

Digital projectors are the best way to get the biggest possible image for a PowerPoint presentation or a movie. But the projectors are often pretty big themselves, with even most “pocket projectors” too big to stuff into the typical pocket or laptop bag.

That is changing. A new miniature-chip technology from Texas Instruments (TXN) called pico is making digital projectors truly portable, instead of merely luggable. For the past couple of weeks, I’ve been using two of the first pico-based projectors on the market, Dell‘s M109S and Optoma’s Pico PK-101.

The products are designed for different customers with different needs. Dell (DELL) positions the 13-ounce M109S as a notebook companion, best suited for work presentations. The four-ounce Optoma projector is designed more as an iPod or digital-camera accessory for watching movies and slide shows on the go.

The Dell M109S

Their portability requires compromises, most obviously in brightness and image resolution. The Dell and Optoma projectors, respectively, support 11 and 50 lumens — a standard measure of projector brightness. That’s far dimmer than top-notch projectors that offer several thousand lumens. So neither product excels in well-lighted rooms, where overhead and ambient lighting overpower their images. You can compensate somewhat for this weakness by placing the devices closer to the surfaces onto which they’re projecting — for example, a wall. But the darker the room you use, the better.

At about the size of a candy bar, the $399 Optoma device is the smaller of the two projectors and the one with the most intriguing possibilities for expanding the tiny screen sizes of mobile devices like the iPod.

It’s powered by a rechargeable battery that Optoma says lasts for an hour on full brightness or two hours on a power-saving setting (the projector comes with two batteries). The projector has a tiny speaker, but people who want decent sound will need to use headphones or external speakers.

In theory, the Optoma device is small enough to bring along on a camping trip to show a film on the side of a tent, or to a restaurant, where you could inflict a vacation slide show on dinner mates by projecting onto a napkin or tablecloth.

I tested it on a recent airplane flight by projecting an episode of “Mad Men” from an iPod touch onto the back of the seat in front of me. The seat was a dark blue with embossing on it, so it didn’t work very well. It’s best to project onto an unmarked, light-colored surface. The quality of the image was better when I lay in bed one night, projecting a video onto a white ceiling.

Even under the most favorable circumstances, however, I found the images from the Optoma projector very dark, muddling the outlines of characters and action on screen. Although Optoma says you can get up to a 60-inch image from the projector, 45 inches was about as big as I could make the image before it got too fuzzy.

Optoma says the projector will ship with an iPod-compatible connector cable when it goes on sale in the U.S. on Dec. 15, though the unit I tested didn’t come with one. I connected the device to my iPod touch using a $50 cable from Apple (AAPL).

Compared with the Optoma device, the $449 Dell M109S is a behemoth, yet it’s still only about the size of a short stack of drink coasters. Most projectors weigh at least a few pounds, if not more, which is big enough to make them a hassle to carry around. I barely noticed the Dell projector inside my laptop bag.

Unlike the Optoma projector, the Dell M109S has to be plugged into an electrical outlet to work. It comes with an unsightly set of connectors for plugging the projector into a video source, such as the VGA port found on most laptops and a composite video plug that is standard on DVD players. I was, however, able to plug my iPod touch into the Dell projector using the $50 Apple cable.

And unlike the Optoma, the Dell doesn’t have speakers. To get sound for a movie, you’ll need headphones or speakers, like those on a laptop.

Despite its extra bulk, the Dell M109S literally outshines the Optoma projector. It produces a bright image that I found very watchable, even if it wasn’t high-definition. I projected the movie “James and the Giant Peach” onto an interior wall of my house, creating an image that was about 7 feet, measured diagonally.

The Dell M109S includes a capability called keystone correction, a standard feature in most projectors that adjusts a projected image to give it the proper dimensions, rather than the trapezoidal shape that results when a projector is angled upward. The Optoma projector doesn’t have this feature. To get a normal rectangular movie image, I had to hold the projector level, toward the projection surface.

For business travelers who do presentations or for people who want to create a theater-like experience in a hotel room, vacation house or against a sheet in the backyard, the Dell projector would be a good fit. For now, the Optoma projector is a good idea that needs refinement.
