Currently on 13.10 at home, 12.10 at work desktop, 12.04 on servers. I feel no need yet to upgrade my desktop and my servers. All my previous upgrades had been motivated by better config tools and installers or new software. All these issues have dealt with by earlier releases. I think the distro is no longer the conduit for delivering new software and 14.04 doesn't bring any compelling upgrades outside of Unity tweaks, which I don't use. I'm going to wait this one out.
