I have both the DP1s and the DP2. I personally prefer the DP2, less color casts, more SD9 color (if you like the SD9 feel, it's my favorite Sigma). I find the 41mm focal length just perfect. The DP2 has fantastic bokeh. I also prefer its handling. But unfortunately it is more expensive than the DP1s. I am also considering selling some of my DSLR gear and regularly bringing a couple of compacts along. Right now my most used combo is the DP2 alongside the Ricoh GXR w/28mm lens. For video and snapshots (with superb IQ for an ultra compact), I take along a Sony TX9.
