I am about to sell my ibook but for the money i'll be recieving i can only afford a Macbook core duo (not core 2 duo). My questions are: Is it worth it, should i really exchange my iBook for a Core duo macBook? Can a macbook core duo definitly run windows better because of the processor? which would you consider better, a refurbished macbook of the apple site a a new one from some other site? Where do you think i can best find the cheapest macbooks, even the core2 duo's. Thanks alot,m appreciated.
