Mark Shuttleworth has announced "Ubuntu for Android", which brings Ubuntu to multi core Android phones.
Ubuntu for Android is a phone but also your own portable computer that you can plug in to any monitor to get a fully featured desktop:
Carry just the phone, and connect it to any monitor to get a full Ubuntu desktop with all the native apps you want, running on the same device at the same time as Android. Magic. Everything important is shared across the desktop and the phone in real time.
Contacts, photos, music etc., will be available on both the phone and the desktop interface.
