I run Ubuntu on my 'not doing much other than youtube and paying my bills' computer. (I also choose to reinstall the whole OS every major release (+ 1 month for those 'day 0' issues to be fixed)).

I have debian on my NAS and 'stable' backup box. I keep this thing rock solid.

If I actually want to do anything crazy, I'll either whip up a VM or I have a clunker of a laptop I keep around for experimenting and other things (along with other single board computers).

My two cents in keeping something stable is don't do anything to it. Keep it as vanilla as possible unless you are 100% sure what you are doing.
