>Does anyone know if there are any devices that use Windows 6.1 Mobile, that are not actually a phone and don't require a cell phone connection? I don't need the thing for calling, but do need it to run a app.

If you decide you really need a physical device (and don't mind an "unsupported" version), let me know. I've got a Dell Axim x51v that you could pick up from me cheap (it's really a nice PDA). There are updates easily available that can reflash it to 6.1. It's just collecting dust now that I've a PDA phone.
