That would be nice to know, wouldn't it? We see things like this every now and then, Ubuntu TV comes to mind, where the idea looks great but at the end of the day it is targeted at OEMs, not the consumer.
I have been looking for a mobile OS that adheres to the principal of least astonishment for a while now, but have come up short. I would pay money.
If you have an Android phone, go to their website; grab the platform binaries, and flash it onto your phone using fastboot. (Disclaimer: you'll have to root your phone first, so be prepped for broken warranties.)
I'm kidding ofcourse. The real answer is, wait until they release some device that supports it!
You don't need root access on whatever OS you're running to unlock fastboot. You typically only need to access fastboot via USB, how else would you load an OS to a blank device?
I'd love to know. I bought an N9 late in the game expecting its "openness" to work with all this year's upcoming mobile OS's, mainly Sailfish. So far all it can run is android.
