Since I've heard (over at thinksecret, as I recall) the new powerbook is the exact same hardware, though with a small increase in CPU speed. As I've got the 1.5Ghz Powerbook, I was wondering: how would it be possible to upgrade it to 1.67Ghz? It couldn't be that hard I figured, as the hardware configuration on the new seems to be the exact same... Any thoughts? I can't be the same who doesn't want to shell out for an entirely new powerbook just to gain a small bit of performance...
