So I installed Ubuntu 14.04 last night. It isn't too bad after disabling a shit load of Unity Scopes. 14.04 seems to be a lil' bit faster than 13.10, window movement most notably. It also seems pretty stable thus far, nothing's crashed yet. All the Steam games I play are working well. World of Warcraft via Crossover WINE 13.0.2 is also running well.
For a few days (or untill I get tired of Ubuntu) the PPSSPP compiles with be done under Ubuntu 14.04.
