a $500 price difference between the base model macbook pro and the midrange model is now about a $200-$300 difference if you get the free ipod touch and sell it off. is it worth it now to go this route? i initially wanted to save some money and get the base model but if any way i can future proof my macbook pro i'm open. i plan on using the MBP for music production so how much will the extra VRAM and L2 cache help?
