I'm getting close to purchasing a black MacBook, but there are many stories of whines, moos, heat, sudden shutdowns, etc. now it's been a while since the MacBook was first released, if I buy a built to order MacBook from Apple.com, am I still risking getting a MacBook with the stated problems? has Apple made any progress on the MacBooks since they first released them? I recall reading a thread on how Apple is already on Rev. D MacBook Pros, they just never announced any of the fixes publicly. have they done the same with the MacBook, or is buying a MacBook tomorrow the same as buying one the first day it came out, thanks.
