If they "don't make it" then I'm fricking sorry but they are too damned stupid to be doing IT, full stop. I have run Win 7 HP on a 2003 Sempron with 1Gb of RAM, that is a lot older than 6 years (6 years would be 2008, which would be in C2D and Athlon X2 territory, both VERY capable CPUs) and ya know what? Ran just fine. On a 6 year old PC, which the average PC at that time were dual cores with 2Gb of RAM and 80-160Gb HDDs? Frankly Windows 7 should fly. Hell its the exact same specs as the main box I use at the shop, a 1.86Ghz C2D with 3Gb of RAM and it runs great, the only thing it didn't run OOTB was Aero but its not like a school box really needs Aero-Flip and transparent tiles does it?
As for TFA? Unless Google is willing to spend billions becoming a national ISP? Then ChromeOS is as good as fucked, and media centric Chromeboxes like TFA will be DOA. I mean did everybody forget about how the ISPs are going to "all you can squeeze" bandwidth caps? Google missed the boat, the future is ISPs giving THEIR services unlimited pipes and screwing the holy hell out of everybody else. These are obviously HTPCs but with everything in the cloud? Yeah hope you like those overage charges friend, as you try to watch HD video with most capped lines and see how quickly you blow through your pittance.
I've seen the future of the HTPC and its some company growing a brain and doing what I've been doing for over a year, just grabbing a copy of OpenELEC and slapping it in a low cost media tank like an AMD Jaguar or one of those embedded Intel Celerons or Atoms and giving folks a nice XBMC that will play pretty much any format from anywhere, be it web, DVD, flash stick, you name it it will play it. With economies of scale there is no reason why you couldn't get it down to the $200 range, maybe even less with a good deal on the chips, and still make a decent profit while selling like hotcakes. It would be the perfect replacement for the DVD player, as it would be able to play anything from anywhere and about as hassle free as using a toaster.
Somebody will pull it off and make a damned nice niche for themselves but it sure as hell won't be running Chrome. Maybe Android but even then not Google's version, more likely their own like kindle so the company can control it, although I still think the smart money would be just to pick up an already finished product like OpenELEC and slap your own brand on it, hell the thing just screams "make me an embedded media OS".
