Fresh data out of market research firm Gartner this week confirms what you already know: Apple (NASDAQ:AAPL) keeps gobbling up market share in the PC industry.

Remember when Apple was a niche player for rich kids, graphic designers, and musicians? The company's thin slice of the computing market was hovering around 3% a few years ago. It's closing in on the double digits today.

Not impressed? Apple moved nearly 30% more units this past quarter than it did a year earlier, and you're just shrugging your shoulders with a Sarah Silverman "whatever" smirk? Is it the 9.5% slice? Did you think it would be more, given all of the "I'm a Mac, I'm a PC" ads you've been consuming? Well, consider that Gartner's preliminary data is expressed in terms of units. Since Apple machines are typically pricier, those premiums mean that Apple has a bigger share of the market when it comes to outright revenue.

Oh, and this is a domestic figure that includes shipments to corporate offices, which usually operate in a Microsoft-flavored (NASDAQ:MSFT) world. For now.

The consumer market trends are even more Apple-riffic. During Tuesday's rollout of the new crop of MacBooks, Apple pointed out how retail market share is up to 17.6% in units and a whopping 31.3% in terms of revenue.

It shouldn't surprise you anymore when you see the huge Apple display at Best Buy (NYSE:BBY). Heck, Best Buy is even selling iPhones these days. Fuddy-duddy office supply chains like Staples (NASDAQ:SPLS) and Office Depot (NYSE:ODP) are another story, but give it time.

The Apple revolution isn't supposed to take place overnight. Then again, going by Gartner's projection of a 29.4% year-over-year spurt for Mac shipments, mainstream acceptance is already here.
