mines a Rev. A macbook pro, so I've had it about 2 years. I love it, and don't see any reason to upgrade right now. There is also the fact that I have a fair amount of school debt, and don't really want any more debt on my shoulders if I don't need to. I figure if it breaks, yeah I'll probably get a new one, but other than that, I'll keep my baby till the day she dies.
