The popular media center XBMC, which started out as a media center for the Xbox, finally got renamed to Kodi Entertainment Centre from version 14("Helix") onwards.
The rename was inveitable since the name XBMC no longer makes sense as it barely runs on the Original Xbox, and also because there would be legal issues in having xbox in its name.
For more information, go to the official blog post or if you want to test out version 14, add their nightly or unstable ppa's to your software sources and install xbmc using
sudo apt-get update && sudo apt-get install xbmc
Download the official 2buntu app for both Android and Ubuntu Touch.
