I know I'm do for a rotation in my computers in the coming months, and not really sure how I want to go about upgrading everything. Just a quick question. I see that with moderate use (half brightness, constant web use) I can expect to get about 4-5hrs of life. When I'm on campus all day writing in the library, I can get away with the lowest brightness setting, and will only use internet to browse flash-free forums and check my email. In that case, any idea how long I might be able to squeeze out of the 11"? Thanks!
