Mark Shuttleworth delivered a keynote on the opening day of the UDS and announced future plans that he has with Ubuntu. Expanding Ubuntu is one of the key goals of Canonical, and they have already started the process to make Ubuntu available in not only desktops and servers, but also phone, tablets, cloud and supercomputers.
"Ubuntu 12.10 was the beginning of this extraordinary push that we are making to create an open platform that spans everything from the phone to the cloud and supercomputers”
He also announced that Ubuntu 14.04 will be an important milestone for Ubuntu in this regard:
“By 14.04 we will be in a position to ask [developers] to deliver a security update, one security update, to phones, laptops, tablets, TVs, PCs, servers, cloud servers and supercomputers. Nobody has ever achieved anything like that in the history of computers."
Further, Shuttleworth seems to have keen interest in Steam for Linux and he said that Steam was the number one requested item for over 8 years.
"I was really delighted to hear news that Valve is bringing Steam to Linux and specifically to Ubuntu, this was the number 1 requested item for the last eight years"
