The prerequisites could be handled in the same way that WP7 handles them already, by warning the user at install time in the store. For example, some apps require a gyroscope, which I think handsets only came out with in the second generation. If you try to install one of these apps in the store, you'll be warned that some functionality won't work (or perhaps won't work at all - I haven't seen this). Similarly, I've seen reports that in the upcoming update aimed at lower end handsets, there'll be warnings in the store for the few apps that don't work with limited ram requirements. I would predict Windows 8 will keep a similar list of the device's capabilities and warn the user in the store if they try to buy something that won't work.

It just warns you and says that "same application featurews may not be supported" or something like that. TouchDevelop and some of the Compass apps do this.

  That's what I was saying. Its still possible to use TouchDevelop and compass apps without the gyroscope, hence why it is only a warning. I was wondering though if there are any apps (or if developers have the option to set this) where an optional device feature such as the gyro is so integral to the app that it won't even install without the device capability. This is what I haven't seen yet - though maybe the marketplace is already filtering them out for me.
