Perhaps, but a core premise of the post-PC world is that people will be increasingly using tablets and smartphones to surf. I doubt that many Windows RT/8(which is supposed to be not selling) tablets have been sold, so it must be PCs(which are supposedly dying off) a few of which were upgraded overtaking the biggest mobile OS in a matter of days. And it must be consumer PCs too, since enterprises aren't deploying Windows 8 in any large number.
You're mixing up evidence here. Android has the largest share of mobile units, but the comparison being made is web traffic. Android's share of mobile web traffic share is not the largest, being only a third that of iOS. In other words: you're overlooking most mobile web traffic to reach your conclusion.

That's a weakly formulated definition. Post-PC is really the new use cases opened up by mobile form factors. Of course it's going to start by evolving from the way we used PCs. But anyone who's surfed on a smartphone out in public will realize that it's something to do "in a pinch" or it's good because some access is better than no access at all. How we end up using mobile in 7 years will be more different from now than how we used the web in 1998 was different from 2005.
"And it must be consumer PCs too, since enterprises aren't deploying Windows 8 in any large number."
Former Microsoftie as of August - this is not true. We had already sold tens of millions of Windows 8 licenses prior to 10/26 as part of our Enterprise Agreement (EA) process with big enterprises. Ballmer mentioned this onstage during his //BUILD keynote too.
Yep, and recoiledsnake's article actually backs this up, since Windows 8 web traffic was already quite high before the 10/26 launch date (according to that statcounter graph, at least).
