when apple switched to intel, i remember the macbook pros having lower specs than my powerbook in some areas: slower super drive, low resolution...
Super drives were the same speed, and the 15.2" PowerBook G4 had a resolution of 1440x960, where as the 15.4" MacBook Pro had a resolution of 1440x900. Not really a significant difference (since MBP is a 16:10 display).
MacBook Pro had faster RAM (667MHz vs the 333MHz in the G4) too.
What were the lower specs in the MacBook Pro then..?
