I was reading this morning an
editorial at BusinessWeek regarding Apple being "too cool" but not delivering new PowerMacs. I have heard that the G4 CPUs are already close to their limit regarding the speeds they can deliver. In the past I wrote an
editorial regarding Apple creating "Macs based on x86/Opteron" but seeing Apple staying faithful to the Motorola CPUs, could the development of multi-CPU Macs could be a (temporary) answer to the G4 speed limit (especially when the G5 is nowhere to be seen)?
