I got mine 2 years now it's a 2,0 Ghz intel core 2 duo and i upgraded it with 4gb of RAM to run OS X Lion smoother and a new 750gb HDD instead of the very small original 125gb HDD. 
But now i'm looking out for a macbook pro 15" i7 but they all are pretty expansive so i'll wait for the new one to wait for the prices to drop
