Very nice of them to have a free community version (security patches 10 days after normal release - this seems fair to me).

I could have used this a year or so ago, but I rewrote an old 2.3 Rails app in Clojure (cookingspace.com if you are curious). Now I am glad it is in Clojure though.

I had previously updated another Rails app from 2.x to 3.x and I was surprised how much trouble it was to do that.
