I'm still relatively new to Apple products. I've only seen a few years worth of revisions and they seem to get better each time (you would expect that!). The Unibody's are a real peace of work. They look great and they feel great. Flex, what's that? I mean this seems like the pinnacle of laptop build. The only problem I see is the reports of the aluminum bending. It appears we traded one problem for another: crack vs bend (plastic vs. aluminum). So where does Apple go from here? What can they do to improve the design or build quality?
