As someone with programming background, I actually wish there are more stories on the opposite direction (programmer who gets kickass awesome in UI design (HTML + CSS)).
I think that the complexity of CSS compatibility (what browser supports what not... even there are minor quirks between Firefox & Chrome, not just IE.. don't get me started on IE7 & 8 either), it is very easy to raise a white flag and say "that is it..I am going back to deal with backend only tasks, nothing that consumer will see on the surface).
Perhaps, OP already has a knack for UI design (as he/she mentioned in the post that he/she is a UI designer by trade before Ruby), so kudos for getting a nice grip on Rails. As for me, I wish I can master the UI design etc.
