What sucks is those three probably count as "sales" of the Vista OS.
That's because they were... sales, that is.
Dunno about anywhere else in the world, but what I'm seeing here in Oz is that all major PC manufacturers/distributors/stores have fully switched to Vista.... no XP machines are being advertised anywhere anymore, not in junk mail, newspapers or on TV. The major retailers who sell propriety brand PC's have stopped selling XP based machines entirely, so it would seem the transition to Vista is fairly much complete here (long before MS' cut-off of June 08)... meaning, like it or not, Oz businesses will have to go with Vista if/when they have to upgrade their hardware.
In fact, the owner of my local (small) PC store told me that he can no longer get XP in the OEM or retail versions from any of the regular distributors, that once his current stock of 17 copies) is gone that's it, no more XP based PC's from him, either.
