Trying to compare specs fo the three macbook models, it seems like a good idea to spend the extra $200 to go from the bottom one to the middle one. You speed goes from 2.1 to 2.4, the hard drive goes from120 to 160, and you can write DVDs instead of just reading them.

But all I see is if I moved from the middle to the top MB is a bigger hard drive (which you can pay $90 for on the middle model) and having a black case instead of white.

Seems like I'd be paying $110 just for a different color case!

Is there something I missed?
