I'm in the market for a new powerbook. It looks to me like the new 1.67 G4's don't look have too much new under the hood (do I REALLY need an extra .17 Ghz in the processor?) and it's a response by Apple to pressure for a new machine. I'm getting the idea that it's not really worth the extra money and that the 1.5 Powerbooks just became a pretty good buy. Any advice?
