Tried out #elementaryOS over the last few days. Comparing it to mainline Gnome3, it's a fair bit slicker. I like the OSX-style dock, and holy crap I've missed column view. On the other hand, some things are frustratingly obtuse: Defaulting to the shortcuts window every time you hit meta, app switching without a pop-up window showing which app you're on, and single-click open in column view are all incredibly frustrating. Charging $5 for a launcher menu editor is also... less than ideal.
And as an aside... let me state just how cool it is that by having /home on a different disk you can be fully up and running after completely replacing your OS in < 30 minutes.
