Well someone local wants to trade their 24" iMac 2.4ghz for my 15" original Macbook Pro. Is this a good trade? How fast are they? Good enough graphics or gaming in Windows? I don't really need the portability as I can basically do everything from my phone. I'd love to get the 27" iMac but I don't want to spend all that money for a new one. Is the 24" a good model? And how nice are the screens?
