re: Windows 8: Microsoft Makes 6 Big Bets
Judging the worth of an argument based on a three-syllable phrase seems a little suspect to me. It's sort of like dismissing someone purely because he's mistaken "who's" for "whose," but I digress.
If your point is that "Post-PC" is a misnomer because tablets are in fact a kind of PC, then sure, that's reasonable. The article even referenced how tablets challenge "how we define what counts as a computer and what doesn't," which is a pretty similar point.
As for Microsoft inventing the tablet... even if you want to take the point of view that Apple just stood on Microsoft's shoulders, that doesn't negate the iPad's relative dominance of the tablet category. It also doesn't negate the fact that Windows tablets have yet to achieve remotely comparable popularity, among consumers or enterprise users. These facts speak to how Apple executed the products differently than Microsoft, and, given the success of Apple's execution, these facts also diminish the importance of who "invented" the concept.
As for Windows 8 being a beautiful OS... sure, for some. And I think we've repeatedly made that point on this site. But just because it's useful for some people doesn't mean that iOS or Android or Chrome OS or OS X or whatever can't be more useful for someone else. And just because some people find it "beautiful" doesn't mean that a lot of intelligent, capable users can't find the OS awkward and unintuitive, or that they can't justifiably prefer some other OS for both work and recreation.
That's really the challenge Microsoft faces. It's not that Windows 8 is unworthy. For some needs, it's the best option on the market. But needs are diverse, and for the first time, we have a diverse assortment of operating systems and devices to serve those needs. Personal computing devices had been pretty homogenous for a long time, with Windows OSes accounting for 90% of the market. But now that desktops and laptops aren't the only devices people use for work, it's natural that no single platform will dominate, especially since Microsoft - despite "inventing" the tablet - was so late to embrace mass market mobile devices.
