Nikon Coolpix A vs X100s vs DP2m Coming very soon.....

This week I bought a Nikon Coolpix A, and a Fujifilm X100s:  How do they compare with the Sigma DP2m Image quality, usability, practicality?  I plan to offer a practical users perspective and I'll have the post ready soon.... Suffice it to say I now only have 2 of these cameras and I think I will keep them for a long time.  (At least until there is a Ricoh GR Digital with a more current sensor).  

Here is a low light example from the X100s at ISO 3200.... 

Fujifilm X100s - Handheld, No Flash, ISO3200, F2.8 1/40sec.
