My early 2008 15" MBP is still kicking, though had quite a few parts changed through the years. Aside from a couple of warranty repairs, it was dropped and get its screen messed up twice. First it was during the warranty period, and although I had to pay for repairs out of pocket, they made sure to note down that my warranty would still be valid for future problems. Then a few months ago I dropped it on the corner again, this time bought the same laptop with a busted logic board from Craigslist and did the brain transplant on it, because both my screen and lower aluminum case were messed up. Now I'm just waiting for my SSD to arrive so I can breathe more life into it.
