It was unclear whether such a move would signal a large-scale shift away from chips made by IBM, Apple's longtime supplier, the article said.One possible reason for the switch, or at least for Apple considering such a swich, could be pricing. The WSJ report apparently speculates that Apple might be able to get better pricing this way, allowing it to compete on price with rivals like Dell.
Apple could choose to add some Intel-based models to its product line or make a complete shift to Intel's chip technology in what would be seen as a serious blow to IBM's chip business, the newspaper said.
Personally, I hope Apple converts to x86 CPUs and even gets into supplying the MacOS for standard PC hardware. They should have done it 20 years ago, but late is better than never.
