I've been using MATE since F16 -skipped F15 because I couldn't stomach the G3 change. I am very pleased to say that MATE has run without a hitch on five machines, 2 AMD desktops, and three ancient Thinkpads, all running F17. I'm hoping people will use MATE and encourage it's development so it will become the live fork that many of us wish G3 had been. No offence meant to G3. This is from a 71yr-old geek who could not code a desktop, but I know what I like.
