Zune as dev/test for WP7 apps

I have a Windows Phone 7 a开发者_Go百科pp to develop as a pet project and was going to get a phone just for testing my application. The app doesn't require calling features, so I was wondering if it would make more sense to get a Zune HD instead of the phone (trying to avoid paying monthly service fees). In short, how close are the Zune HD and a windows phone 7 for testing simple "lob" type applications that would ultimately be sold as a windows phone 7 app?

This won't work since the apps need to run on the Phone O/S, which does not run on Zune devices. Nice idea though.

The Zune HD is a much slower processor than the Windows Phone 7 CPUs. The Zune HD runs at 600 mHz whereas the Windows Phone 7 devices all run at a gigahertz.

It's also not running the right operating system.

You might be able to test the games on the Zune HD. It uses XNA as does the Phone. The speeds (as above) would be different, but in theory this would work.

One can hope that perhaps a Zune HD2 might be in the works.
