My original macbookpro is still alive and well and withstood very heavy use. Granted, I needed to replace the battery a few times, originally because mine was within the serial # range of defective batteries, but each time those changes were covered by my warranty. The computer is now almost four years old.

I suspect that you can find someone with an anecdote describing a perfectly functioning mac and one that exploded. The same such anecdotes likely also exist for people running Thinkpads, Latitudes, et al.
