It is still hundreds of millions. All enterprises sit on Windows, most home users too. There is no way out for enterprises and so far Linux has failed to convince home users, despite numerous Ubuntu like efforts and even free commercial distributions being available.
And Vista, eh, Win XP was there in 2001-2007, while Vista's was 2007-2009. If Win7 wouldn't follow, we'd be stuck with Vista.
Except they said something else:
Valve began some exploratory work with Xi3 last year, but
currently has no involvement in any product of theirs,

In other words, they worked, then got pissed of at each other.
Xi's response:
""We reaffirm the fact that
we received an investment from Valve Corporation (as we previously disclosed during the 2013 International CES trade show), and we did so with Valve's written permission," said founder, president and CEO of Xi3 Jason A. Sullivan in the statement. "Second,
we were asked to build a product specifically for Valve, and both companies showcased this product the Piston console in their respective booths at CES 2013.""

So, they've tried it, they got to a point when they demoed it, and then it appeared to be a lol product at a lol price.
That's VERY UN-SERIOUS in my books. And why be serious if you have no serious competition? (50-70% of the digital distribution market is Valve's as estimated by Forbes)
My interest, as a customer, is getting rid of DirectX exclusiveness on PC, which is only possible by either boosting OpenGL or some new lib.
Boosting Valve, already dominant player on PC gaming market, is not.
How long did it take Microsoft (which was part of OpenGL group by the way) to make DirectX what it is now? And that's Microsoft, which is oh so much bigger than Valve.
I might have missed what is so great about it? Remote desktop part? There are PLENTY solutions, some of them of 1-3 guys team scale, some 1 guy scale. Is there something SERIOUS, something that definitely could not be done by 1-3 volunteers?
In other words, Valve did a good thing that lets people who run Linux discover that remote desktop client is available... Seriously? =)
As someone who actually TRIED connecting PC to a TV, I can share my experience with it. I didn't even need remote desktop or anything like that adding serious lag. I just used long HDMI/USB cables, just to discover that I can't comfortably play PC games on a TV, because most of them assume you sit next to the screen.
