Atention! I just read and I don't believe it. Bodhi Linux, an Ubuntu based distro, has been ported to Raspberry Pi.
I honestly do not believe me just yet (especially being the April fool's day). As discussed is quite stable, and completely moving environment with OpenGL, so the speed must be amazing.
I think Raspbian now has a serious competitor if all the talk about this is true.
Keep you informed about this great operating system over the week.
