It might take a few years for Microsoft to adjust, iterate and revise, but I don't think they will let Windows 8 fail. Recall that it took the XBOX a few years to break into a market with two, very strong, established players (Nintendo, SONY) and now XBOX is leading that market.
Except Windows RT cannot, and Windows 8 can...
Some of these articles from 'so called' techies over the last week or so are really starting to feel like a bit of a click through bandwagon.
And Windows RT and WinRT are different things.
And there's new tablet offerings of Windows 8 that will be Windows 8 (not just look like them with the Metr... Modern UI) in a few months. If I didn't know that, I'd be pissed in a few months. If I do know that, I'll probably wait to see what the options and pricing are in a few months.
Even for those 'in the know', there's a lot of confusion and decision making.
EDIT: I say this as someone who has fond memories of MS from many years ago, became an antiMS bigot for a bit, and now just would like to see them succeed. Not as a huge fanboy so much, but as someone who likes to see a marketplace of good options/ideas. MS has often botched good tech seemingly because of internal politics, and that's sad to see.
So you'll need to wait if you specifically want the Microsoft Surface Pro, but you'll have other choices starting on Friday. In fact there will be more x86 devices than ARM devices shipping with Windows 8 this week.
Customers won't care. Most people don't follow the development of a software product and will call it Windows 8. If they need to differentiate between the desktop and the new interface they'll come up with their own way to describe it (the tile interface for example).
>> "And Windows RT and WinRT are different things."
Windows RT is the tablet operating system. WinRT is the Windows Run Time something customers will never hear mentioned and never care about.
As for the 'full' Windows 8 tablets vs the arm Windows RT ones I don't think consumers will care either. Most people will probably try it before buying, see what it can do, and as long as it still does that when they get it home they'll be happy. Full Windows 8 tablets will be quite a bit more expensive by the sounds of things anyway so they'll be aimed at a different market.
And the average consumer knows nothing about ARM or x86 so that isn't exactly a good way to state the difference.
