Apple plans to move lower-end computers such as the Mac Mini from IBM to Intel chips in mid-2006 and higher-end models such as the Power Mac in mid-2007. The announcement is expected Monday at Apple’s Worldwide Developer Conference in San Francisco, at which Chief Executive Steve Jobs is giving the keynote speech. The relationship between Apple and IBM has been rocky at times. Apple openly criticized IBM for chip delivery problems, though Big Blue said it fixed the issue. More recent concerns, which helped spur the Intel deal, included tension between Apple’s desire for a wide variety of PowerPC processors and IBM’s concerns about the profitability of a low-volume business. Over the years, Apple has discussed potential deals with Intel and AMD.
