twitter's Journal: Windows in Decline, as More than 1 in 3 PCs Ship Without 7

As the Linux Foundation wins new friends and influences people, sharp reporters at PCWorld notice that Windows sales as a fraction of PCs shipped are in a steep and accelerating decline. Woody Leonhard of Infoworld does the math on Microsoft's numbers,

Between launch and June 30, 2010 -- a period of 251 days -- Microsoft sold 0.78 Windows 7 licenses for each PC sold. Between July 1, 2010, and April 22, 2011 -- a period of 275 days -- Microsoft sold 0.67 Windows 7 licenses for each PC sold: 175 million Windows 7 licenses, and 260 million new PCs. To turn the numbers the other way around, in the past nine months, more than one-third of all new PCs sold didn't have Windows 7. ... it's entirely possible that 40 percent of all new PCs in the past nine months shipped without Windows 7. Maybe more.

So, the Windows 7 PC sales "refresh" is over. Business adoption rates are still under 10%. Kanthryn Noyles of Computer World interprets that as a Win for gnu/linux

I think it's fair to assume that a good number of them are running Linux instead. Preloaded options, after all, are increasingly common, and the reasons to switch are more compelling with each passing Patch Tuesday.

Android/Linux, is another reason for the decline. Why sit around mom's basement with a big, noisy PC when you can drop the net in your pocket? PCs are less important and Windows is downright archaic.

Microsoft's bottom line sags with its cash cow. There was good evidence in 2010 and January of this year that Windows 7 was not driving sales. Roughly Drafted now looks at Microsoft's quarterly report and shows that Windows profits are down since 2008 back when they were trying to sell Vista which many people dumped in less than six months.
