Why GNOME refugees love Xfce (Register)

"Unity seems to be aimed at using less screen real estate (especially vertical). However, XFCE can quickly be configured to use one auto-hiding vertical panel which is ideal for a widescreen laptop or netbook."

Amen to that, use it on widescreens, netbooks, and dual head setups. Been using that configuration since the Afterstep/Wharf days. Easy switch to XFCE. Definitely a superior experience compared to MS Windows/Gnome/KDE, or OSX.
