I think that graphic designers probably have more difficulty sleeping than I do; I don't obsessively notice imperfections. Problems with interfaces do annoy me, but I'm more interested in raising the general, average awareness of this discipline than in chasing a vague ideal. I see more and more apps these days that each have some tiny little wonderful touch in them, and that delights me.

To answer a slightly different question, I'm very satisfied that people are more aware of quality user experience, and that customers are more willing to demand it, and blame the designer rather than themselves when something doesn't make sense.
