Update: I tested the battery today. Suppose to get 7 hours of battery, and I got 5. I guess this isn't too bad considering the screen is on full brightness and I was downloading the entire time.
I had a 19" mac book pro and sold it because the battery life was horrible. Also, I ran windows mostly because I was always using AutoCAD so seem worthless. I purchased the hp tablet touchsmart tm2 for the replacement. Awesome computer the screen has a bad glare due to the touchscreen. Battery life was great and computer ran like a champ with the 6gb of ram. So between the glare and stupid windows errors here and there, I'm going back mac!
