Sorry Google, no.
And "no" for exactly the same reasons as to why your Chromebooks never really took off. I just don't want my applications and/or data held to ransom either by yourself, or an internet connection - especially if I am paying to play. If I'm paying £50 for a software title, I'm happy to do an initial install from the internet, but as I only tend to play single player games - I want the software installed locally so if I want to come back to it in a year or so, I know it will still be there.
Also, for well understood and documented reasons I simply don't trust you with any of my data.
So in a nutshell - fuck off Google.
