I don't see win2000 or vista or 8 in that list. Not including those demonstrates within your anecdote that Microsoft is capable of putting out shitty half-step OS's that people pretty widely dislike.

That's what 11 feels like. In ten years people will be fighting the move from 12 to whatever is next, and people might not even talk about 11. Like they don't talk about 8.

That's because, like with the pattern of those other three disliked OS's, Microsoft is going to to have to be reminded that people won't just accept a polished turd. They will actually have to make a good OS with a reason to upgrade.
