I am planning on buying a macbook in the near future. I really want the white one, but if it is still having problems with turning yellow on the track pad, and arm rests, I will go with the black. However, I am trying to stay away from that because I don't want to shell out an extra $200. I haven't come across many recent posts about this problem, and I was wondering if it has been resolved for the newer models. I would greatly appreciate any insight!
