The App store, as well as Android Marketplace, needs a systematic way to try an app on a trial basis. Right now, all risk is on the customer. If you buy an app and it doesn’t meet your needs, you are just out the price of the app, with apparently, no recourse. It’s really difficult to tell from comments and screen shots whether a given app is any good, or whether it will work for you. iTunes lets you hear a good part of a song before you buy. Apple should extend this idea to apps, by allowing a trial period.
Some publishers publish a trial or free version of their app, but what I’m looking for is a general scheme that works for all apps. I would be much more likely to buy a paid app, especially a more expensive one, if I could try it first.
Does anyone know of any existing way to do this?

I don’t think they want trial versions because people would buy less software. That’s probably why they make it hard to submit/find trial software.
It would make the App Store a big mess. I like the way Apple has it.
