That’s not accelerating growth folks. It has flattened considerably to about 50million per quarter when the world is selling 90million PCs per quarter, about 55% attachment rate. What’s on those other PCs? It can’t be Vista because the webstats say it’s in decline. It can’t be XP because the webstats say it’s in decline. It can’t be MacOS because Apple is shipping only 4.3% of the world’s notebook/desktop PCs. That leaves GNU/Linux and FreeDOS, folks.
UPDATE Lenovo ships a bunch of PCs with no OS and discourages people from buying if they have a volume licensing agreement with M$. So, it appears the missing PCs are not getting that treatment from businesses. The mystery deepens.
UPDATE This is a clue. At the bend in the curve sales of PCs with XP and retail sales of Vista were stopped…
|Desktop operating systems||Date of general availability||Retail software end of sales||End of sales for PCs with Windows preinstalled|
|Windows XP||December 31, 2001||June 30, 2008||October 22, 2010|
|Windows Vista||January 30, 2007||October 22, 2010||October 22, 2011|
|Windows 7||October 22, 2009||To be determined||To be determined|
So Vista has been tapered off for several quarters. It cannot be the cause of the decline… Wait! At the bend in the curve ended sales of PCs with XP installed and end of retail sales of Vista! Now “7” has to go along on its own and it sells fewer PCs as a result.
