I have a white MacBook that's about a year old, and it's already taken quite a beating. I've been in school, and admittedly I have been pretty rough on it. But there are scratches in the white lacquer, and more disturbingly, there are some cracks in the case, near the trackpad. Since the black MacBook doesn't have the same glossy finish, you won't have the same type of exterior scratches. But I doubt build quality is actually much different between the two. I'd be wary of buying another MacBook. The MacBook Air is only about $300 more, but all reports indicate that the build quality is phenomenal. (Same with the MacBook Pro.) If you're going to be using the laptop on the road, and you want to keep it a few years, then I'd spend the extra money for the Air. Plus, you're clearly more excited about the MacBook Air... so go for it! :)
