Battery Life: 4:24
Cost Per Hour of Juice: $45 per hour
Lets take a look at two Chromebooks with around the same price: the Samsung Series 3 Chromebook ($249) and Acer C7 ($199). Both devices sport 11-inch displays, but the ARM-powered Chromebook lasted 7:34, while the C7 lagged more than 3 hours behind at 4:24. Granted, the C7 isn't designed to be your primary PC, and maybe you will use it mostly around the house. But why would you pay $45 per hour of battery life for the Acer when, for just $50 more, you can get the much more efficient, $33-per-hour Samsung Chromebook? The Series 3 also happens to sport a sleeker design.
