I decided to go the LTS route as well. I actually don't know when they will actually release the new version, but I assume it will be before the end of April (do they always hit their target release month?).

I will be upgrading fairly early; probably at the end of April. I have a big deadline in late April and upgrading Ubuntu will be my reward/punishment. I suppose I will listen for any disgruntled users before I make the plunge, however, and reassess if things look too problematic.

Note: this is for a work machine, but a PC, not a server or something like that.
