Does anybody know why, after all these technological improvements, the macbook got a significant drop in weight while the macbook pro didn't drop at all? It seems strange to think that the weight is the same. I would say "it's the glass!", but the macbooks have glass too and they don't weigh as much. I really can't imagine what could be in the MBPs to make them weigh 1 pound more than the macbooks when, in the past, they were nearly the same weight.
