I'm starting college in the fall; I was wondering if my MacBook Air would last at least a class session ( say 2 hours to be safe ) on battery life to take notes and what not. Apple says the battery is 5 hours but lets be realistic now. This is the sole reason I am feeling the 13" MBP. Anyone had any actual experiences with the 10 hr battery life apple claims it to have? And how is it for classroom? Or is the MacBook Air enough? Thanks for the help guys.
