Hey! What kind of backpacks do you guys use for your MBP? I have a 2.4 17', and I really would like a backpack. I looked at www.booqbags.com, and they're packs are pretty sweet; although, they are a bit expensive. Does anyone have one and would like to give me some reviews on it? Also... Has anyone tried css on the 2.4 SR MBP yet? I just want to know how much FPS this baby will get... Thanks!
