This Reuters story quotes Steve Jobs regarding the possibility of OS X on Intel:
Some analysts have also urged Apple to move to microchips from Intel Corp. INTC.O from those made by Motorola Inc. MOT.N and International Business Machines Corp. IBM.N to cut costs.
Asked about that possibility, Jobs said that first the company had to finish the transition to the OS X operating system, expected around the end of this year.
"Then we'll have options, and we like to have options," he said.
