Almost Like New, Again

The front edge of the right palm rest on my 4-year old MacBook started to chip again, exposing a gap in the case through which dust could enter. Once again, the Apple Store replaced the entire top plate, including keyboard and trackpad, at no charge. This time they did it in under two hours despite the store being very busy. This, for a computer I had bought refurbished online, that was three years out of warranty. I'm very impressed.
