The biggest one I'm looking forward to is the stabilization of btrfs. Other than that, though, I think it's mainly an evolutionary release. I typically reinstall from baremetal, but when I went F18 --> F19, I thought I'd try to fedup (Fedora Upgrade) process. It worked well, but my system now has leftover stuff from two versions (stuff I install to play with, then remove--leaving old dependencies behind), so it's time for a fresh metal install.

IO think 1 of the biggest problems (minus the easy access app windows), is the fact you have to input the password for anything that may or will affect the system.
I outgrew that prob... we just need to get the rest of the entitlement generation to accept an understand .... (so many curse words left out :p)
BTW.. there is so much difference in respond time here, compared to ANY LINUX forums...
Here... 1-20 minutes... ANY Linux Forums... 1 day-5 years :/
