Scottsdale, from the look of your post I can tell that you know zilch about the 12" Powerbook, or should I say, "Glorified iBook". The 12" Powerbook had so little in common with the 15" and 17" Powerbooks. There was nothing "Power" about the 12" Powerbook. You guys are trashing the 13" MBP, but in fact it's much more inline with the 15" and 17" MBP then the 12" Powerbook ever was with the rest of the Power line.
The 13" MBP is FAR from a glorified Macbook.
To play devils advocate, upon the PowerBook 12" release it had a G4 processor, whilst the iBook still had the G3, granted some stuff was gimped in comparison to the 15" and 17" models, and once the iBook went G4 there was little difference, much like the current MB 13" and MBP 13" now.
On a side note I've always taken the view that the extra bits in the 13" MBP are just things Apple have dropped from the MB to upsell to people, it's something they've mastered over the years, as they have a long record of nixing features from certain models to get you to buy that more expensive one. But judging by their profits it seems to work
