Amazon Boosts Kindle Battery Life, Adds Native PDF Reader

Amazon has added a native PDF reader to its Kindle 2 e-reader, making it only the second device in the Kindle family to boast this feature. The Seattle-based company also announced a much enhanced battery life for the Kindle 2. The longer battery life, it says, is the fruit of a six-month-long firmware improvement program.

According to Amazon, it has managed to extend the Kindle’s battery life by 85 percent, which translates to seven days on a single charge with wireless turned on. But apparently Amazon’s firmware improvement program failed to yield any such improvements in battery performance when the wireless is turned off. These enhancements will be delivered  to existing Kindle owners as part of  a firmware update. Some earlier versions of the device will also be receiving native PDF supports via Whispernet wireless.

Barnes and Noble is facing an enviable predicament, that of failing to keep the Nook in stock. But Amazon made it very clear in a press release that the “Kindle is in stock and available for immediate shipment today.”

In Test Windows 7 Netbooks Take Battery Life Hit

A new round of testing by Laptop Magazine indicates that battery life on Windows 7 may not be all it’s cracked up to be. Microsoft claimed that their new OS would result in better battery performance on some netbooks. The testing, however, says otherwise.

Three netbooks were tested: the Toshiba mini NB205, ASUS Eee PC 1008HA, and the HP Mini 311. On average, the computers ran down 47 minutes sooner with Windows 7 than with XP. Still, two of the units were running after nearly five hours, and the Toshiba made it nearly nine hours on Windows 7. It may not be the same as losing nearly an hour on a conventional laptop, but it is something to consider. If you plan to buy a netbook, will you be hunting for one running Windows XP?

Review: eMachines G725-422G25Mi

The eMachines brand is a sub-division of Acer and offers a more affordable alternative to its consumer Aspire laptops. The G725-422G25Mi is a large-screen, entry-level media centre and is a good choice for those seeking a desktop replacement on a budget.

The 17.3-inch Super-TFT screen is well suited to entertainment use. Its widescreen aspect ratio is ideal for watching DVDs and its increased width also makes it easy to simultaneously work with multiple windows side by side.

Image quality is mixed. The panel is very bright, but this leads to a slightly washed out appearance. Colour and contrast are excellent, however, so photos and videos look great and the sharp 1600 x 900-pixel resolution provides detailed images.

Sturdy chassis

The plain black chassis uses sturdy plastics throughout and is tough enough for family use. The textured lid is resilient to scratches, although it builds static and quickly attracts dust.

Build quality is strong throughout, but this is partly due to the chassis being thick and bulky. Thanks to the large chassis, the keyboard is spacious.

emachines detail

All keys are tapered at the edges, making them comfortable and easy to work on. The board has a soft typing action, however, which creates a spongy feeling when typing. Irritatingly, the keys also rattle slightly.

Mobility is surprisingly strong despite the chassis weighing 2.8kg, the 234-minute battery life ample for life on the road. As long as you don’t mind the weight, you can comfortably work for half a day at home or on the move before you’ll need to recharge the battery.

Performance is fairly solid. The dual-core Intel Pentium processor provides power for home use and even basic photo editing. As with all laptops at this price, however, there is unfortunately not enough power for complex multi-tasking.

The 250GB hard drive provides ample storage and will hold thousands of photos, songs and videos. The dual-layer DVD rewriter lets you save files to CD and DVD and a 5-in-1 card reader is fitted at the front of the chassis for access to the most popular media card formats.

Unfortunately, this is the only laptop here not to feature an integrated camera or ExpressCard slot. Also, there are only two USB ports, although software for basic home office tasks and creating CDs and DVDs is included for new users.

While the power and battery life of the G725 are excellent, the flawed usability and features limit it slightly, so consider your needs to decide which factors are most important to you.

MSI Wind U123


Large and in charge

MSI’s latest venture into the netbook market offers slightly faster performance than the rest of the netbooks we’ve tested with much longer battery life to boot, but the nine-cell battery that makes that possible sends the MSI Wind U123 into the heavyweight range. It makes us wonder: How heavy can a netbook become before it stops really being a netbook? Do we buy them for their formfactor or their performance? Or is it just the price?

The battery is the first thing we noticed about our Wind review unit. The dang thing juts from the back of the netbook, raising the back end more than an inch from horizontal and adding more than a pound to the total weight—making the lap weight three pounds, four ounces. But it’s worth it if battery performance is king. In our full-screen DVD-video battery rundown test, the U123 far outlasted the competition, achieving just over seven hours of playback. The previous netbook record was shared by two Eee PCs, the 901 and 1000HE, both of which clocked in at five and a half hours. This means a nine-cell-powered Wind U123 will likely get eight to nine hours of light usage on a single charge.

Battery life wasn’t the only area in which the Wind U123 outperformed the competition, though. In both Photoshop and our newly instituted Quake III benchmark, it squeaked out small but perceptible leads on the competition—beating our previous Photoshop winner, the Asus Eee 1000HE, by five percent, and running Quake III 5fps faster than the Samsung NC10.


If you don’t mind a bit of junk in the trunk, the Wind U123’s nine-cell battery will fast win you over.

The Wind U123’s internals are exactly what we’d expect from this newer generation of netbooks: 1.66GHz Intel Atom N280 CPU, 1GB DDR2/667 RAM, 160GB 5,400rpm hard drive, Bluetooth 2.0, and 802.11b/g wireless card. Its external features are similarly standard: three USB 2.0 ports, a multicard slot, VGA, audio in/out, and 10/100 Ethernet. The LED backlight on the Wind U123’s screen is one of the brightest we’ve seen on a netbook; at 60 percent it was brighter than the 1000HE at 100 percent.

MSI has outfitted the U123’s lid with a color scheme it calls Midnight Blue—we call it Sparkly Blue Fingerprint Magnet. The rest of the netbook is matte black and much more smudge-resistant, except for the LCD bezel and the area above the function keys, which are glossy black, and the touchpad buttons, which have a brushed-metal look. The touchpad itself is responsive, if a bit small; you have to download drivers if you want to enable touchpad scrolling. The keyboard is a standard scissor-switch mechanism keyboard, as opposed to the chiclet keys we’re used to seeing on netbooks these days, but it’s quite comfortable to type on, and is nearly full-size. Indeed, our only gripe is the same one we have with every MSI keyboard: the damn Function key is where the Ctrl key should be, and vice versa. This has screwed us up more times than the 1040-EZ.

The Wind U123 boasts user-upgradeable memory and hard drive, though it involves removing 10 screws and punching through a warranty sticker, then removing the entire bottom of the chassis. At least you don’t have to take the whole computer apart, as with the original Acer Aspire One, but it’s not exactly as simple as removing two screws and popping off a panel, à la the Asus Eee 1000HE.

The Wind U123 brings a lot of muscle to the netbook arena: It’s slightly faster and has a much longer battery life than any we’ve previously tested, though the nine-cell battery adds bulk to the otherwise sleek netbook. And the bright screen is sure to win fans. But there are certainly netbooks out there that are lighter, easier to upgrade, and offer similar performance, even if they can’t quite match the battery life.
