Yes, scanR may be more sophisticated in their image processing technology, but their system is just not as easy to use (the last time I checked it out).

My suggestion to you is to keep running with your idea of making your service dead simple to use. I love the idea of just sending it to an email address -- reminds me of posterous, but for image processing.

Yes, like Posterous has shown, simple can win you converts even if it's lacking functionality.
