As we developed the app model for Windows 8 and the new Metro style apps, a key architectural requirement has been to deliver apps to customers that can be used with confidence--confidence that apps will be well-behaved with respect to resources, that apps will not interfere with other apps, that apps use system resources with your permission, that apps can be installed and uninstalled with ease, and so on.
