In a question-and-answer session on Reddit Wednesday, Microsoft's Surface Pro team ignored most questions about the tablet's battery life, but hinted that the company might sell an add-on battery pack in the future.



From Computerworld:

"If you compare it to say a MacBook Air, you will quickly see that pound for pound in battery size versus battery life, you will find optimizations that puts Surface best in its class," the team told the Reddit "Ask Me Almost Anything" (AMAA) audience. "That said, we picked a smaller battery to be sure we were able to give you the same performance and to keep it thin."

Apple's 11-in. MacBook Air, the closest Apple product in specifications to the Surface Pro, is marketed with a promise of 5 hours of battery life.
