Best compact companion for DP1/2?

Say you have a DP1 or DP2 and you want a compact camera to complement it.
What would you go for, and why?

After getting my DP1 I'm neglecting my DSLR more and more. I really enjoy not having to carry around 3-4 pounds of camera and lenses.

But of course there are areas where the DP1 isn't optimal. For my next trip I'm going to bring a Canon S95 to use for situations where I really want some zoom or otherwise feel restricted by the DP1.
