I realize this isn't about an Apple tablet, but it's about the latest 13-inch Macbook Air. It runs a new Intel Core i5 processor, if I recall correctly. Cnet tested the device and it ran for EIGHTEEN HOURS on a streaming video loop. That's absolutely unheard of and even beats the low-powered Asus Chromebook C200, which gets 11-12 hours of battery life. Even if that figure it somewhat smaller, it still should get more than 10 hours for all types of usage except the heaviest multitasking. That's pretty darn impressive, and I'm a huge fan of great battery life.
