My 13" MacBook pro still works as good as the day I bought it, and its now 2 generations old. My old laptop was 2/3rds the price, lasted a year before the hinge cracked, and wasn't as nice to use. I still use my iPod video 5G from like 6-7years ago.
The Pro (aluminium cased) models weren't too bad (although I think they're a bit overpriced), but the old regular plastic-cased MacBooks seemed to have used an inferior plastic composition and tend to crack around the edges. A quick search on the Internet of "macbook crack" shows this defect clearly.
I prefer Thinkpads, never had any problems with them.
Yeah thinkpads are tough as shit
