Ubuntu isn’t exactly a stranger to the mobile space — it started showing off its Ubuntu for Android project in early 2012, but it wasn’t about to stop there. Not long after teasing the prospect of a touch-friendly future for its peculiarly-named OS, Canonical has officially pulled back the curtains on its Ubuntu phone OS and it looks, well, great.
That beauty comes from the fact that it doesn’t really look like any other mobile UI out there right now — it eschews the traditional app grid concept that pervades iOS and stock Android and instead relies on horizontal swipes to view oft-used applications and switch between currently running ones. In a way, it’s approach is more reminiscent of Windows Phone 8 and Windows RT than either of the two leading mobile OSes, though whether those UI decisions catch on is another story entirely. Still, the end result is an interface that feels more spacious and expansive than its potential rivals, a tricky proposition when hardware designers struggle to balance device screen size and portability.
Honestly it looks fantastic and I love that its Linux based however there is no more room in the already competitive mobile os wars. I loved the desktop idea as well.
I only use Ubuntu for Virtual Machines 
It's too inconvenient to use for daily use.
