I'll also re-post what I said in another recent thread.

I've had a macbook for a year and a half now, and I've never had any problems with it, ever. Ok, well, I filled up the memory on it but I have a LOT on it. Also, if you let it go past the "reserve battery" message until you run out of battery, it has to sit quite a while before it comes to life again, but other than that I've never had any problems at all with it. It starts up really quick.
