Ubuntu For Android (Not Ubuntu Installer)
The guys over at Ubuntu are developing something REALLY nice for the Android that are able to support both HDMI and USB, which I think the PLAY is capable of. This is some legit stuff guys! Time to revolutionize!
It says that it's for multi-core phones, but maybe this could be ported to work on the PLAY in the long run? Discuss here!
EDIT: Something already popped into my head, since other Ubuntu distros can already be merged with the original Ubuntu itself, do you think removing the Android Ubuntu elements and adding them to a desktop Ubuntu system, then connecting the phone via USB with Debugging enabled would do the trick?
