I think a trial is a good idea. Though screenshots seem to be fair warning against lousy apps. For instance, a lot of lousy apps "waste" 2 or 3 of their screenshots with obscure details or marketing slides because (I assume) they don't really have much in the app itself to show off. Any time I've seen 5 full-screen, detailed, unique, functional screen shots I haven't really been disappointed; a quality app doesn't have any trouble looking that way. I think developers probably have a little too much leeway over what they can change (since you can't really "go back" once you "upgrade"). For instance, I've seen games change fairly substantially compared to their original versions a year ago, and sometimes it's for the worse.
