Found it on DPR: The Sony Cyber-shot DSC-RX100 – a somewhat comparative review
A great overview. I'm only about 1/2 way through, but thought I should share. He also compares to the LX5, XZ-1 and GRD.
This is the kind of review that I like.
I am nearly certain I'll have this camera, once they start showing up on Amazon warehouse deals. I'll probably drop my kit lens for m43, and maybe also my 14mm.
