Not at all, in fact I'm hoping I can move everyone to desktop Linux eventually. I will not buy XP machines. If I'm forced to buy Windows it will be Windows 2000.
The truth is, the only decent UI to date technically is WPS, and that has usage issues for the hoi polloi.
MS is too dumb to have a master plan. Have you ever seen anyone actually USE Active Desktop? For all practical purposes, IE is used like any other application - in spite of it really being welded to the OS. Windows is a stupid as ever, with no well-defined line between the hardware and the UI - it's just more stable now, after 8 years of the same thing. (It amazes me that in all this time, a decent competitor has not emerged.)
