Ubuntu is set to take the world by storm this year by coming to smartphones, smart TVs and more desktops than ever before. Now it’s time for Ubuntu to tackle the final frontier.

Canonical announced today that its bringing Ubuntu to tablets. The Ubuntu tablet combines the best desktop and smartphone UIs have to offer and combines them into a cohesive interface that offers maximum usability. It’s the continuation of Canonical’s philosophy that Ubuntu should remain the same across all devices with only a changing interface to reflect the platform its currently on.

Check out a quick video tour of Ubuntu for tablets below:

The most interesting feature of Ubuntu for tablets is the new “side stage” feature that promises to improve multitasking on tablets. Here’s the breakdown:

Ubuntu’s unique side stage places a phone and a tablet app on the same screen at the same time for amazing tablet productivity. True multitasking comes to the tablet. Take calls in Skype while you work in a document, make notes on the side while you surf the web, tweet while you watch a movie. Or use apps collaboratively – drag content from one app to another for a super-productive day. We’ve reinvented the tablet as a bridge between phone and PC.

Ubuntu for smartphones will be out in October of this year, but it’s still unknown which territories it will be initially launching in. I would presume that Ubuntu for tablets would be on a similar schedule, but it’s still up in the air at this point.

That being said, Canonical is inviting developers to start making apps for Ubuntu on phones and tablets for when they become available. You can grab the preview mobile SDK here.
