If you are not a developer but thinking of installing some apps to try that are not available from MarketPlace, you can now get access to them via ChevronWP7 Labs.
It cost USD9 a Windows Phone 7 and you will need to log in with your Windows Live account. Since the release of ChevronWP7 Labs, it has been updated to resolve some issues.
There are some home-brew applications that I am already interested (like Screen Capture and Folders).
