I would agree that he sounds right...even though i really hope hes not and we get g5 powerbooks soon!!!
very unlikely though
look at barefeats.com. they compared a PB G4 1.5 Ghz with a imac G5 1.8 Ghz in appleworks, photoshop, imovie. the imac is between 0% and 30% faster than the pB. that is not a lot given that the clockspeed alone makes 20%. so all the other processor features (esp. FSB) lead at best to an additional 10% performance increase. when you compare then a 1.7 PB to the 1.8 imac there will be no noticable speed difference.
so whats the point in getting a G5 PB?
because of the heatproblems it most likely will be a 1.6 or 1.8 G5 at best and therefore not faster than a G4 1.7. especially when the G4 at some point will be dual core.
its pure speculation on my part but if apple had committed to the g4 for their consumer line Motorola probably had worked out versions of the G4 with slightly higher FSB, dual core and 2.0 GHz by now. i would be happy with that because i don't need the 64 bit. i'd prefer a faster imac G4 2.0 GHz dualcore over a imac G5 all the time. but maybe i'm missing something.
i'm just very impressed that the ancient G4 still can play in the same league as the G5s (30% speed difference between 1.5 PB and 1.8 imac isn't that much).
