I've yet to have any of the Apple laptops that I've owned (or desktops for that matter) that have broken in that timeframe. In fact I'm using an MBP that's going on it's fifth year here, and the only thing that's changed is I popped in a new battery after about four years. Excellent track record for me. (Of course, YMMV.)

I've never seen one break long after that. In fact, I finally just had to part ways with an iBook from 2001 that lasted me over a decade, and upgraded from 9.2 to 10.5.

Using a 2008 MBP. No issues. Of course, I have now given it to a mom who is happily using it.

And this was the macbook pro with a GPU that had a high rate of failure (8600M GT)

My 2008 MBP has never had any issues.

Still on a Macbook Mid-2007 on Mountain Lion with the original battery! :)
