I went to the Apple store to mess around, I saw the MacBook and fell in love with it. I'm looking to buy one.. what are the differences between the pro and the regular? I know the screen size and GHZ.. is the extra $1000 worth it? would I be able to upgrade the mac with a GeForce 6600 graphics card and a gig of RAM I already have? I don't plan to game on it.. maybe CS 1.6 (which is WIN98) every now and then.. (I don't know much if anything about laptops) should I buy one off of ebay or the apple store? order it? buy a used one? soo many questions sorry.. I don't want to spend $2000 on something which wont be useful to me.
