I have been using, and was very happy with, Fedora/Gnome for many years (since day one in fact). It did everything well and was stable, with steady incremental development. There was no reason to look elsewhere.
Until F15/Gnome 3 that is. What a disaster! even the fallback mode.
I quickly moved to Mint with Gnome 2.32 (a good distro, but its not fedora) while investigating other options. Now I have installed the Fedora 16/Xfce spin on my machines. (The fact that xfce is good enough for Linus was a factor!).
Wow! Wow! I should have changed to xfce years ago! Its very very fast, does everything I need, and does some things
better than Gnome 2 IMHO. My older athlon xp box is now snappy and responsive like my Core i7/SSD.
Thunar, xfburn, parole, terminal etc are all well designed, lightweight and productive. I love odd features like being able to configure terminal with terminalrc (configure it once and copy the file around). The custom date format in the date plugin is genius (once I realised it was strftime).
I am very happy having now found a perfect DE again, I can just hope and pray the developers wont get itchy fingers and succumb to the bloat and radical change that has ruined Gnome and KDE!
Brilliant desktop - my thanks to all those who produced it.
