hey guys I need some suggestions.. I have a white macbook its the SantaRosa Chip 2.2Ghz, 120gb HD and 4 gigs of memory.. Now there is someone that has a 20" iMac 2.0 Ghz, 250gb HD and 2 gigs of memory and wireless keyboard and mouse, that would like to trade it for my macbook. So my question is.. would I see a big difference of performance going from 2.2 to 2.0? do you guys think its a nice deal doing a even trade? The only reason why i wanna trade is because i would love the bigger screen and i normally dont take the macbook outside like I tought would... Thanks for the advice in advanced
