I've been considering trading my mid-2009 MacBook Pro 15" C2D 2.53 GHz 8GB laptop for an iMac for it's screen size and because I'm already using my laptop as a desktop pretty much and I have a MacBook Air for portability. I've gotten a hit on Craigslist to trade for a 2008 iMac 24" C2D 3.06GHz 4GB. What are you opinions on this? Should I make the trade? Why or why not?
