I've been using the beta for a month or two now, and I must say that I'm impressed. I didn't think I'd like the new shell in Gnome 3, but I don't have any complaints and is actually pretty slick. I'm running it on a T420 and it supports all the hardware perfectly and seems to get better battery life than Kubuntu (Maybe different kernel version or something...).

I love being able to install any needed development tools with a simple "sudo yum install".
