Aside from the private bits, I think just face/eyelids. I have seen a few nice looking face tattoos that weren't obtrusive though, but eyelids always look tacky to me. I probably shouldn't have done my neck, especially at my age, but ah well. One of my, if not my favorite, "possessions".
And the only way I'd tattoo the side of one of my fingers is if I were to do a lightsaber. Only good sidefinger tattoo I've seen, personally.
