The next big decision, in fact, is how to merge the 2D and 3D versions, Shuttleworth said, and it's a tough one that will require developers to redo some work.
Quality, however, is continuously improving thanks to the fact that there's now significant QA support for the interface, he added.
"It seems people who were even very skeptical about Unity are willing to give it another shot," Shuttleworth said. "I think the design vision is becoming clearer, and the team worked incredibly hard to address bugs and shortcomings."
3. Wayland is on the way. The new Wayland graphics system announced in late 2010 "will be exactly two years more mature for the next LTS," Shuttleworth said.
At the same time, "I think X apps will be supported well beyond that, and we'll make the pieces fit together smoothly along the way," he added.
4. A new icon theme? Canonical has long wanted to create a new icon theme, but a proper analysis needs to be done before anything is actually implemented, Shuttleworth said. Toward that end, "we've pulled together some experts, both artists and interface gurus, to look at the use of icons across the desktop. The art part will come later," he noted.
5. Microsoft's "gutsy choices." Asked about Windows 8 and any opportunity it may present for Ubuntu, Shuttleworth remained diplomatic.
"I admire some of the gutsy choices Microsoft are making," he said. "It's difficult for them, and they are doing some things very well. Credit where it is due."
"We are not here because we hate anybody else," Shuttleworth added. "We're here because we have a vision of a future only we can create."
