Mini HTPC users: account configuration?

To all those who use a Mini as a home theater PC, how do you have your accounts setup? I mean, do you just use a regular account for playing media, and have other accounts for config, etc.? Right now, on my Mini (server version), I just have a single admin account that I do everything through. It seems to work fine but the power went out one day and while it turned back on, it stopped with the login screen (so iTunes was no longer being served up since it has to run as a user).

That got me thinking if I should have it automatically login but then I wasn't sure if I really want it to automatically login an admin account. There aren't other family members running around, so that's not really the concern - more, I guess, if it was stolen.

Anyway, how's your setup?
