Just a quick question before I bite the bullet tomorrow... I am not a gamer and will be using the macbook for web browsing email music photo and imovie and Apple TV. Also I will be running vista and windows xp. My question is Am I going to really be missing something when the new macbooks come out. Will it really make a diffrence for what I will be using my macbook now??? Also how good is the aero effect on the macbook? is it too slow?? thanks for your insight!!
