sorry for making a new thread, but i just wanted to ask what exactly the santa rosa chips will do when they are included in the macbooks? I ask this because at my local Comp USA they have the 10% off closing sale, and i wana take advantage of the small but good savings. I just went to the store and test drived my first mac, and all i got to say is they are lighting fast, even the standard Mac Mini is faster than my current PC. I honestly cant see how faster these beasts can get. so this is why im asking what exactly they will do, because if its just a speed boost, then i think ill just buy one of the current models because those seem fast enough for me.
