I think a lot of the people who write articles like this forget that Windows 7 still exists for the "hard-core desktop users" (yes, I claim I fall into that category, although I'm an Xubuntu user as well). Realistically though, Windows 7 is on extended support until 2020, so that's 8 solid years of use remaining. And for an OS that currently holds around half of the entire market, I'd say we're far from a "post-Windows" world.
And assuming this picture is accurate, then Windows 8 will actually be very good for Microsoft; who wouldn't love to have an x86-based Windows 8 tablet that can do as much as a full-fledged desktop (albeit with a bit less performance)?
