I like many are/were hoping for a iMac G5. And I'll admit that I lust after the new PM G5's, but can't justify the overall cost. Been looking at XBench marks for various systems. My PB 12" rev. B ranks in at 97. It appears that the newer PB's with the G4 1.5 rank in at 130, and the older single G5 1.6 in at 150. It would seem that there is little rational for the G5 processor right now. Once OSX goes 64bit and apps do the same that should shift. Is my thinking correct?
