WSJ.com - Apple Eyes Shifting Macintosh Line To Intel Chips: "Apple had been a particularly high-profile customer for IBM. But the big computer maker has recently had success in convincing Microsoft, Sony Corp. and Nintendo Co. to use PowerPC technology in their next-generation video machines, a business that is expected to dwarf sales for Apple's hardware over the next few years.
Apple last quarter sold 43% more Macs than it did in the year-earlier quarter, quadruple the pace of the industry as a whole. But the company had just 2.3% of new world-wide PC sales in the first three months of the year from 2% the prior quarter. Windows PCs account for the vast majority of the rest of the market."
