The geekiest of the operating systems is branching out into entertainment. Ubuntu TV is the open-source answer to your living room set-up, and you could have a TV running the software by the end of the year.
Ubuntu TV is a TV-optimized version of the desktop OS, based around the Unity UI. It feature full-on media center and DVR features, including movie, TV and music stores, and a YouTube app. The idea is to make the OS free for manufacturers to package with their TVs, and Ubuntu says there will be TVs on shelves by the end of the year.
