So I have loaded a dual boot of Ubuntu 11.04 and Chrome OS on my CR-48. This is the first time I have seen Unity on Ubuntu, man is it different. It will take some getting used to. All seems to be working fine, the trackpad is still a little wanky but it is like that in Chrome OS so I guess I can’t ask for much. It really did not take long to install and it seems to be working really well. I will have to look into getting a larger SSD drive, maybe something like this for the laptop as it only comes with a 16GB.
Will check back with you after a day of so running Ubuntu on this little guy.
