Fedora 16 up and running.
Initial thoughts:
Not much different use and appearence wise than Ubuntu. It runs on Gnome 3 which is nice, Unity sucked. My Broadcom wireless was a nightmare to get installed, but that was me getting use to the system. I needed PAE drivers and didn't know it.
MUCH faster, and everything works. The computer wakes from sleep, by function keys are spot on, etc etc.
Predictions:
I think I will be wiping Ubuntu off within a week and sticking with Fedora and Win7
