After the Plasma 5 fiasco, which wasn't ready for production, really, I took the plunge and switched to Kubuntu 14.04 LTS. It sucks to update your distro every 6 months, and it sucks even more to update distros having the feeling that one is in permanent beta. Nowadays I don't care about "beautiful desktop" and bells and whistles in general, I just need a stable and working environment. Still thinking what to do with wifey's notebook, though. But I'll probably go through the same route.
