definately the turion. you'll kick yourself later when you realize you get crap battery life. i agree with laptop extreme, the pentium M tends to do a little better on battery. I'm on my pentium M 1.6 lappy right now and i use it 100x more than my pentium 2.8 ghz lappy. in other words its not getting used much at all. its fast as hell but i can't stand the 1 hour battery life.
