Other than the processor updgrade? I'm trying to decide between a 2nd gen black macbook with 2.0 C2D and a 3rd gen black macbook with a 2.16 C2D. If the only difference is the .16ghz more and slightly more HDD space, I think I would rather save a few hundred bucks and get the older model. However, if there are any differences in quality or battery life, then I would opt for the newer/better one. Thanks.
