I just bought (less than a month ago ) a 1.67 PB and my battery life is horrible. The only time I can get 5 hour battery life is when the LCD backlight is off (it's unusable)! I wanted the advertised 5.5 hour or close to it so I could get through all my classes everyday, but with 1.5-2.5 hour average I can barely get through one class! The final selling point between an IBM laptop (so I could run all of my current apps) and PB was the battery life. Watching a DVD I get less than 2 hours and same with just surfing the internet with one app open. I can't use the computer on much less than the maximum screen brightness due to eye problems. The macbook pro would be the perfect solution with longer battery life and a brighter screen. Do you think if I made my case to apple I could pay to upgrade to a macbook pro at the same price? I'm also screwed on resale value ebay, 15" 1.67 512mb PB went from $1800+on 1-9-06 to $1200-$1500 on 1-10-05!! Thanks!
