For Microsoft, convincing people that Windows is buggy is profitable. An article I wrote last year, Microsoft Windows XP "end of life" [futurepower.net], makes the point that Microsoft fixed 319+828+459=1,606 bugs in Windows XP since Windows XP SP1 was released. Now Microsoft says Windows XP is still too buggy to use. We have 16 computers running Windows XP and haven't had any problems. And software does not have an "end of life", it continues to do what it always did.
