∞ Study: Mac claims 20 percent US consumer market share

Apple COO Tim Cook took the stage at Apple’s “Back to the Mac” event on Wednesday. He shared some statistics to put today’s announcement in context.

[ad#Google Adsense 300×250 in story]Mac sales made up 33 percent of Apple’s revenue last year, according to Cook – $22 billion in sales. Apple counts its Mac installed user base at almost 50 million users. What’s more, the Mac has outpaced the rest of the personal computer market for 18 quarters in row. Perhaps most astonishingly, Cook pointed to a study from market research firm NPD that pegs Apple’s current share of the US consumer retail market at 20.7 percent.

There are 600,000 registered Mac developers presently, according to Cook, and that rate is increasing at 30,000 developers a month. The Mac is also the number one rated computer on the ACSI, a consumer satisfaction index, according to Cook, for the 7th year in a row.
