For December I am going totally traditional Gnome 2 set up with two panels (one at top one at the bottom) on aging Acer Aspire 5532 notebook. Just like last month, I am running lubuntu 13.04 as the base, with everything relating to lubuntu removed and Mate desktop installed. Theme wise I have Radiance as the controls, with Bluebird as the window borders, with Faenza-Radiance as the icon set. Wallpaper is Ubuntu graffiti.
Yeah I know pirated copy of XP is free, but so is Ubuntu and it's LEGAL!
Looks like a lot of Cinnamon this month. Here is mine.
Intel ® P4 Extreme Edition 3.4 (Gallatin) || DFI ® LanParty PRO875B rev B1
Crucial ® Ballistix Tracer PC4000 1GB || Mountain Mods U2-UFO Opti-1203
XFX 7600GT 560M AGP (PV-T73A-UDF3) || Corsair HX520W Modular PSU
Ubuntu 13.10 x64.
Pretty much stock other than the wallpaper and I hid the keyboard icon in the panel. This was an upgrade install from 13.04 with very good results.
