Im thinking of selling my unibody macbook pro 2.4 4 gb ddr 3 ram and buying a new imac 2.66 with 4 gigs of ram and a macbook air. Now i dont game much on my pc but i do occasionally like to play WOW and cs source. Is the macbook pro that much better than the Imac? or will i not notice a different in day to day tasks, the imacs always seem speedier in the apple store then the pro;s
