Query: Very nice when it is working

I just wrote this review for almost the exact same notebook as this one:I really enjoy my iBook when it works. I not very computer savy and it is perfect for a novice like me. My main complaint is that I have had to send it back twice for repairs. The first time the screen died. I mean just died. I turned it on, heard a pop, and that was it. Sending it back wasn't much trouble, but by the time I got it back about three weeks had passed. Then it stop booting and made a funny grinding noise. They sent me a new hard drive (quickly this time) but that didn't do the trick. I just sent the whole thing back and I haven't got it back yet. So I love it, but I really wish it was more reliable.
