Indeed - I have more than a few apps on my iPod Touch that I've used once...and never again. It's quite irritating actually how there are no trial apps in Apple's ecosystem. They know that sales will go down, and thus profits, if people download a trial app and then realize they don't like it/don't need it. That's one of the things I really like about the Windows Phone 7 marketplace; trials are available for many apps.
