Apple's vice president of worldwide product marketing Phil Schiller claims the company is "committed" to the PowerPC chip – yet made no mention of Motorola during an in-depth interview with IDG title, InfoWorld.

InfoWorld is publishing a series of features examining Apple, its operating system and its plans for Bluetooth implementation.

Schiller was asked: "How committed is Motorola to Apple, and how portable is Mac OS X to other chips?"

Schiller answered: "Apple is very committed to PowerPC. That's obviously what we've been doing for many, many years and it's what we will continue to do. We just rolled out the fastest Mac ever – the dual 1.25Ghz Power Mac, so Apple remains on that path."

The question follows weeks of speculation into the suitability of IBM's new PowerPC chip, the PowerPC 970. This processor has features that could be of use to Apple. Motorola's progress on delivering a G5 processor has apparently stalled.

Schiller explains: "OS X is by its very design and nature, portable and we've always said that we've got the capabilities in there to do whatever we want whenever we want to. But the plan remains in PowerPC today."
