My recipe:

Easy Debian, Android, Maemo/Meego i.e all bases covered for third party apps and not needing to learn Python.
Not hearing negative things like why would you want to have a 'substandard' OS on this device (Android)

Basic smartphone features.
Not hearing why would you want bluetooth mouse when you have touch screen, portrait texting when you have a hardware keyboard or a decent GPS program. Not hearing I only make one call a day, so it doesn't really affect me (this doesn't surprise me btw).

Basic communication and love from Nokia.

And a 4 inch screen

Just great and not unreasonable IMO
