Twenty years of Macintosh

Apple's business has always relied on unique advantages over the competition. Over its life, the Macintosh has had many such advantages, yet the platform has never had a large share of the market. Today, Macs are about 2% of the market - about 3 million units a year out of about 150 million personal computers. Apple's revenue share is much higher, however, because its systems are more expensive than the average PC. Protecting its small niche requires Apple to be unusually innovative. In fact, Apple consistently outinnovates its larger competitors. Since 1984 the Mac's computational power, memory, storage and communication bandwidth have each increased several thousandfold.
