if they used the G3fx it wouldn't be so bad. you'd have iBooks that outpace the G4 book, but marketing would never allow that, even though "pro" users choose iBooks over PowerBooks anyway.
here's what we should have, based on sales...
iBook 1.3GHz
1.3GHz IBM PowerPC 750fx or 875
Standard with 512MB
40GB HD
CDRW/DVD
Radeon 7500 with 64MB
PowerBook G4 1GHz
1GHz Moto PPC 7475
512 or 768MB RAM
60 GB HD
Superdrive
Radeon 7500 with 128MB
But apple marketing feeds us the "G4 is for pros" line, even though there exist Altivec-enabled G3s that can mop the floor with it. God forbid the marketeers look bad
