I always make sure the interface actions and flow is near perfect even before I even begin to develop. Artwork and graphics are easily changed at any time, but how the user interacts with the interface is much more complicated and much more important. If you piss off the early adopters, they aren't coming back and you're going up a creek without a paddle.
