Very few people "know" rsync's interface. Any time I want to do anything more than -avz, I have to look it up. A well-made GUI would mean that instead of looking up "what option or combination of options does this?", you could just find the label that says "does this". Of course, this GUI seems to only have the few most common options (i.e. the ones people are likely to remember), which indeed makes it pretty useless.
