I'm pretty certain the UI does matter to more than you make out. I just don't think they know how to express it. From what I've seen, getting the UI right is half the battle--look at MySpace vs Facebook. Though I am certainly seeing where you're coming from with second part. It is a hassle that I don't think most would embark upon. I don't know but it seems switching emails could be a problem that needs solving. There certainly are ways I can think of that would make this easier.
