No, I'll stick with the LTS version a while. So far I've seen nothing compelling in 10.10 anyway. A few cosmetic changes, and maybe a few others I can upgrade individually in 10.04.
I'm sticking with LTS too. Seems like new kernel+x.org have some problems with non-intel graphic cards. Now Ati works, NV doesn't. I tried the RC on my notebook, didn't notice any changes.
