I guess this is a question regarding the older mac owners, because I actually want to get a good view on the issues. Some say the plastic is better, and some say the aluminum is better. I personally came in with a Rev B white macbook, and it was perfect until is started cracking. I bought a Rev C black macbook, and that was perfect until 2 battery defects and then...cracking. BUT I want to know what were the initial problems in the beginning for both: plastic macbooks and aluminum macbooks. Considering the amount of problems the white macbook core duo had in the past, it sure seems like the aluminum is doing a hell of a job with quality (though we do have bad seeds).
