I have an alienware m11x that can get about 2.5 hours of Mass Effect 2 on battery, but I'd like to take my Mac along with me instead from now on. Reason why I ask is I like to game on plane trips across country. Screen is normally set pretty dim and wireless is off. With an advertised 7 hour battery I'd guess it could do 2 hours at least under this kind of load but if someone has tested I thought I'd ask.
