What do I think ? Easy to install, hard to disable Unity, some programs crash sometimes and some things are weird. Despite that I have the faith in the Ubuntu folks that the system would be ready when 11.10 comes.
As whining itself never got anybody anywhere, I’ve reported all of these here:
I’ve even got one OOPS. However, since I’m writing this post under 11.10, it seems usable, even the OOPS was not of disturbance as it got nice GUI window displayed and no system crash then.
