I would genuinely like the option to use GNOME 3. I'm considering moving to Fedora to try it.

It would also be great to see Systemd used. Rather than Upstart.

A global menu and a launcher (like Gnome Do) are some of the first things I install after upgrading. Along with Docky.

I realise some of these are fundamental changes to the Ubuntu way, but it's what is drawing towards alternatives, and further from Ubuntu (which I've used since Warty).
