I'd have to disagree with this. Have you owned one of the plastic Macbooks? Regardless of it being plastic it was still the toughest notebook I had owned to date. Yes, the Pro's are MUCH tougher and I'm glad I upgraded when I did, but I had no complaints or issues with the build quality of my plastic Macbook. It was a great machine.

My comparison was HP's, Dell's, and even an IBM that all ended up falling apart with only a few years of regular use. With the Macbook this was not so.
