I don't run jolicloud as it doesn't fit my need, but I am also interested how well it performs. They claim to have very good gma500 support with a cleaner codebase.

Shouldn't this be in the linux section?

A post over there at ubuntuforums.org:
I really tried almost any distro (including puppy, fedora, mandrake, pepermint,..) on AO751h, believe me, only Jolicloud and ubuntu 9.04 (mind the kernel!), and the new live CD 10.04 work ok without too much trouble. The last one is by far the easiest to install and maintain. Jolicloud has the best hardware support, but personally I do not like to install apps via "the cloud".
However, keep in mind that this was not running on a fitPC2 but on a AO751h.
