Jono Bacon writes "This week at Mobile World Congress both Firefox OS and Ubuntu have been wooing the audience with their mobile offerings. CNET reviewed both and felt that Ubuntu was 'the clear winner.' From the article, 'The team thought that Ubuntu Touch, the tablet version of which we got our hands-on for the first time at MWC, feels more like the complete package at this point. We liked its slick, elegant interface that makes use of every side of the screen and puts your content and contacts front and center, minimizing the time spent hopping back to a home screen.'" They still liked Firefox OS though, and the mere existence of multiple Free Software mobile systems with carrier support is a good sign if you ask me.
