As already teased and promised, today Canonical is taking the wraps off the mobile version of Ubuntu, which is built around the existing Android kernel and drivers, but doesn't use a Java Virtual Machine and promises to use "the full power of the phone." Supporting both ARM and x86 processors, the Ubuntu phone OS will be compatible enough to let Android phone makers run it on their devices with minimal adaptation.Ubuntu for Android, announced in February of last year, will be the first step to getting this new ecosystem out to shipping devices, which Canonical chief Mark Shuttleworth says will definitely arrive at some point during this year.
