Like someone once said, "All good things must come to an end...". I like the polycarbonate better. I just like the look of it. Aluminum's cool, don't get me wrong, but I will not shell out another 1.6K (either the backlit keyboard or not at all) when mine is perfectly fine, apart from normal signs of usage. I think Apple will keep the white macbook, and possible the black, but turn them into netbooks. Someone said that before, and I very much agree. Aluminum for a netbook is way to costly and overkill.
