who is getting this?? I just bought a new Macbook Pro this week but as much as I love it, I still need to plus it 2-3 hours into(Full use tho) it's use. The up to 10 hours of use is obviously for standby time? What is the average battery use time you get when using the computer fully WITHOUT being plugged? is there anything that I can do to make it last longer? Thanks a lot.
