hi everybody, today is the last chance to trade in my macbook to turn it into a pro. I love the macbook but in the graphics department it just doesn't survive. I have a couple wuestions about the pro. 1) does it scratch as easy cuase just basic use on the macbook looks like i took steel wool to it. 2)Batter life, any way to get to 4-4.5 hours i get on macbook? underclocking? 3)Also can anyone recomend a sleve, im just putting my macbook in my backpack. Thanks for all help in advance.
