Goodness! Ubuntu 11.10, "Oneiric Ocelot", is closer than I realized.
I'm undecided about what I will do. I don't care much for the "Unity" UI, and I am utterly disgusted with GNOME 3 and the "we know better than you do what you should have" and "letting people change things is bad, because you can't trust them not to do something evil, and because changing things hides the sheer greatness of the GNOME 3 experience" attitude of the people responsible for it. I may switch to another Linux distribution, or I may just upgrade and stick with other window managers/windowing environments. Linux gives me that choice, among many others, and I'm grateful for that.
