It would provide a nice HTML frontend but it can be a must have extension for Chromebooks
I have in mind a Chrome Pixel running Android virtualized with VGA Passthrough as one of the fastest hybrids.
And of course some GNU/Linux or MS WOS or even OSX running at future hybrid Chromebooks
Samsung has just begin to pre install Android virtualized at their MS WOS 8 hybrids, but I think QEMU can do it with a linux kernel as host with better performance
