Whether you want to use Microsoft's new Windows Vista operating system or not, you're almost certainly going to get it if you buy a new Windows laptop. While reviews of Vista have been mixed, one thing is certain: some of Vista's features, such as the Aero interface and Windows Sidebar, can suck the life out of a laptop battery in no time.

Larry Drury, an Illinois lawyer, has filed a lawsuit on behalf of iPhone owner Jose Trujillo that claims Apple defrauded his client by failing to reveal that the iPhone battery was not user-replaceable, and that it would die after 300 charges. (Thanks, Gizmodo.)

"This case arises out of Defendants' purposeful and fraudulent concealment to purchasers of its iPhone cellular telephone that they will be required to incur an annual fee of $85.95 as part of Defendants' battery replacement program," Drury … Read more

Tesla Motors, the guys with the all-electric sports car, have set a goal of manufacturing 800 cars in their first production year.

The company has already taken deposits for more than 560 2008 Tesla Roadsters, according to a spokesman. The cars sell for $98,000 after a recent price hike from $92,000. If they sell all 800, that will lead to revenue of around $76 million, by my math (average price of 95K x 800).

The company has raised more than $40 million in venture funding.

The Roadster runs on lithium ion batteries and can go from zero to … Read more

When I served in the U.S. Army back in the waning days of the Cold War, about the only battery-operated equipment I needed to worry about taking into the field was the standard-issue L-shaped flashlight, the one with the red lens we needed to swap in to reduce the risk of (a) night blindness and (b) giving away our position to the bad guys.

Things are a lot different now. While the Army is still a long ways off from its Land Warrior, Future Combat Systems and related "every soldier a sensor" goals, today's GIs pack … Read more

Immediately after we posted our Apple iPhone review, Senior Editor Donald Bell and I handed our iPhone off to CNET Labs for battery drain tests. And now we can report that our first results are in.

Replacing the battery on an iPhone will be an expensive and nerve-wracking experience.

Apple revealed the details behind its iPhone battery replacement program this week. It's basically the same deal as with the iPod, in that you have to return the unit to Apple for battery replacement, but it's a little more expensive. The service costs $79 plus $6.95 for shipping to replace the battery on an out-of-warranty iPhone, and Apple says it will take three business days.

The service is also similar to the iPod in that all data is cleared from the iPhone during the … Read more
