I think the dock is really cool, but I can't help but feel that it is a screen space hog. Sometimes I hide it, and sometimes I have it automatically appear. But I find these solutions are never totally ideal. The dock seems confusing to some people. My elderly father for example gets confused with it because the running apps 'light' isn't very clear, and some programs create a second icon in the dock when they are running. So, if you could redesign the dock to make it usability friendly how would you do it?
