* All the non-standard thinkpad buttons - external monitor, volume etc
* USB bluetooth adaptor
* External bluetooth trackpad (Apple)
* 3G dongle - this was not only autodetected, but popped up a wizard that asked me to identify my carrier, and then proceeded to configure everything and just magically brought up the internets
Anyone who doesn't think this is a big deal has not been running linux for very long :-P
Personally, I still replace Unity with Gnome3, but that's a single add-repo and package install, taking about 2 minutes. Unity is significantly better with each release, if that continues I'll probably go back to it in a few versions.
I don't get the vitriol either. Slackware and Debian are still around if Ubuntu is too n00bish for you; personally I'm old and I want shit to just work. Haters gonna hate I suppose.
