I'm running Ubuntu 14.04 LTS right now since, aside from Arch, it's the only distro that just seems to work with my old, crappy hardware. But I'm planning on going back to XFCE instead of Unity. Mainly because opening the Unity launcher doesn't bring me to my applications right away, I either have to search for what I want or click through to applications > expand all applications before I can open whatever I'm looking for.
