Just one caveat to the white MacBook... the case is prone to cracking.
I've read many threads at Apple and other places complaining about cracks in various places on the outer case. But the good news is that Apple is replacing the parts for free even in out of warranty situations.
My niece bought one in August and at Christmas brought her MacBook to show my Mom (trying to see if the screen was big enough for Mom's eyes). She purchased a hard shell protector for the Mac but nonetheless she had a small split in the case near the latch. I told her that I had read about the problem and to take it to the nearest Apple store. She did and they fixed it promptly.
So keep that in mind, but it otherwise is a good value.
