I am so digging the current white MacBook right now. The value is great now that it has the 9400m. I personally would choose it over the alum MacBook anyday.
I am going to buy a white model when I transfer to a university next semester(can't be seen walking around campus carrying an iMac everywhere I go lol). Hopefully by then it will get a minor speed bump.
[EDIT] Now that I think about it, that speed bump probably wont happen until after the back to school special. Ah well...
