I'm thinking about buying a new pb in couple of days. But I found that the FSB speed on pbs (also on ibooks) is really low at 166MHz, waaaaay too lower than other Wintel notebooks i think. So why is that? Isn't FSB speed important on pbs for its "special architecture"? Will pbs with such a low FSB speed will be a lot slower than Wintel notebooks? I mean, a 15'' new pb with 2gb ram & 128 video ram?
