That's nice and all, but this is almost meaningless. For 25 years, we've had monthly articles in the Microsoft-funded trade press about how Microsoft has all the market share for computers. The implication, as always, is not to bother buying a Mac, or, eww!, using Linux. All of these numbers, for over 2 decades, have been buoyed by corporate purchases, and mean nothing. As as Unix sysadmin, and one of the most-ardent Linux zealots, inside a Fortune 250 in the late 90's and early 00's, even I had to admit that it would have been a mistake to deploy the majority of the "corporate fleet" with anything other than Windows. But if you could ever excise the corporate purchasing data out of these numbers, I think you'd find that Windows has less than 50% of the PERSONAL computing market these days. Maybe even closer to just 25%. I base this on personal observation. Almost no one I know uses a Windows-based computer for their "computer" needs. I've posted about this before, to crickets. If we could get personal buying data from, say, Best Buy and the like, and leave Ziff-Davis and Gartner out of it, I think I could prove it. But I'm sure they're taking money from Microsoft to continue to put the numbers together, so we'll never get the "internal" numbers to figure it out from them.
