I was just thinking about all of this and I realized - The fastest G4 we have ever seen in the flesh was 1.42 Ghz G4 that was released last January... and in a year, the G4 has gone nowhere, and it ahs eve, decreased in speed... the fastest G4 chip apple sells right now is at 1.33 Ghz. Is G4 development stopped? We were supposed to see Motorola 7457s but those seem to have never materialized, correct me if I'm wrong... So what's going on? We now have reports of a G3+ altivec IBM thing, but apparently it won't be shipping for another 3 quarters... so what's going to happen to the Powerbooks if they don't go G5, the iMac, etc? The iBook and eMac can still go up a notch to the old 1.25 even 1.42 Ghz G4's if they show up ever again... but might 1.42 ghz be the limit of the G4?
