Do I need DME or ADF in an IFR-certified GPS panel?

Looking for thoughts out there...

If I have an IFR-certified GPS (terminal, not just enroute), is there any
reason to keep a DME or ADF in the panel? (Other than being able to listen
to am radio or tracking "non-offical" navaids - e.g., am radio stations!)

I would say that it depends on how important it is to you to have a
ground based alternative to GPS in case it becomes unusable (equipment
failure, RAIM, whatever) and what ground based alternatives are
available where you fly. In much of the US, there's little point in
having an ADF. In more remote places...
