Power Mac Demand Exceeds Production -- In what might be described as the same old song on a new processor, Apple confirmed last week that it is struggling to keep up with demand for Power Macs and plans to step up production. Historically, Apple has rarely been able to meet customer demand for its machines, much to the frustration of users and dealers alike. But the sheer size of the demand might come as a surprise. More than half of Apple's units are Power Macs; production of Power Macs have more than doubled since a year ago; and over two million Power Macintosh units have shipped since introduction. Additionally, Apple noted the Macintosh installed base now exceeds 20 million machines, double what it was three years ago. Nonetheless, the total personal computer market continues to grow at similar rates, leaving Apple consistently hovering at around ten percent of market share. [GD]
