ChrUbuntu is currently the only distro available for a Chromebook laptop. I have Kubuntu running on my Toshiba Dev machine, and still Windows 8 on my gaming laptop (all the games running on it require Windows--they ran in linux but very poorly and lacked acceleration and anti-aliasing) Currently the only playable games running in Linux are steam games and Wine-enabled games like Star Trek Online and Rigs of Rods. those two play pretty well but i still had to skimp on graphics. too high and it performs like a 486SX
the rest is Android which is sorta Linux.
i don't hate Unity so much, it kinda reminds me of Mac OS X. i don't like how the dock is locked on the left side taking up screen space when i'd want it on the bottom like a taskbar but that's about it. perhaps it's just the distro i'm using that has all that noob stuff turned on by default.
