Went to the Tivoli gardens in Copenhagen today, brought the RX100 and I'm more than happy with it.
It was a joy to work with, didn't balk once in the cold (-5 to -10ish Celcius), and with the Gariz soft shutter (thanks for the tip Amin!) I had no problems shooting it wearing gloves.
I shot most of it in RAW + JPEG mode, but ended up using mostly JPEGs, including a few in camera HDRs.
