I've been using Fedora since... RedHat 4.2. The drop that filled the glass last week (using a nightly compose) was the new gnome3 behavior when coming back from turned off monitor to save power. Even though I disabled lock/screen saver/password, rather than just letting me continue where I was now I have to "slide" with my mouse the screen.
So I switched to Ubuntu. My first ever Ubuntu install. When asking about local time, it recognized the city where I was. Because, gee, I'm connected to the network. I learned how to use apt* stuff instead of yum&rpm, and I don't miss Fedora.
