Now that always struck me as a bit strange, sitting here in olde England. Having a cup of tea in Starbucks I see plenty of laptops running Windows, but not nearly as many Macs as I'd expect if those figures were accurate. One in 10 of the machines in the place? Not a chance!
Seems I'm not alone in noticing that Macs are most notable in many parts of the world by their non-presence: Since most Mac buyers are — apparently — in North America, and since much of the data that Net Applications uses comes from North America, Net Applications has changed the way it measures market share to take into account geographical variations. It turns out that Apple's actual market share has been greatly exaggerated.
The revised figures are a catastrophe for Apple. For the company's fanboys and girls, it's a case of red faces all round. Far from breaking into double digits, Apple's market share estimate has been slashed by more than 50 percent to well under 5 percent of the operating system market. Windows has shot up from the high 80s to over 93 percent of the market; Linux gets a heartening 18 percent boost, putting it safely over the 1 percent mark, with OS X firmly back in its sights.
Now, of course, one can discuss Net Applications' methodology endlessly and question the credibility of any organization that has to revise its figures by as much as 50 percent. But that's all rather missing the important point.
The point is that America's purchasing patterns aren't necessarily the same as the rest of the world's. Here's another example of this phenomenon: It may seem like everybody loves — and has — an iPhone, but worldwide, its share is just 2 percent of the phone market. It's much more accurate to say that everyone actually loves a Nokia. Crazy, but true.
