hopefully some bright folk will work out how to get this onto current Android based phones.
From what I see on the Ubuntu site that is what 'Ubuntu for Android' is. Just requires a beefy enough phone with the HDMI and USB.
Was sort of hoping the S3 could hack it but I think the outputs are the limiting thing. There this 'MHL to HDMI' adapter that goes in to the micro-USB but then I don't think there is anywhere to plug a USB hub in to for keyboard and mouse
