Jon Rubinstein, Apple’s senior vice president of Hardware Engineering,
told Macworld UK that making a PowerBook G5 is simply “an issue of good, solid engineering.”
The catch is that the current crop of G5s are designed for desktop machines, and a cooler version of the processor is needed, he added. On the other hand, Rubinstein told Macworld UK that only a few years ago it was deemed near impossible to get a G4 processor in a PowerBook.
In speaking of the G5, Rubinstein suggested that improving the performance of software to take advantage of the new processor should be “relatively easy,” Macworld UK reports. Apple provides developers with tools to help locate the sections of their applications that will benefit most from recompiling for the G5, he added.
