We must have different sized hands. ;-) The RX100 felt unworkably too small for me. The X2 is very comfortable, particularly when I fit a half case on it. I kinda like that the X2 is 'pure still camera' ... I only very rarely use the video capture mode on either of my other two cameras that have it.
I have to agree with you there... while I decided to sell my X2 because the X100 was too close and more my style, I always loved that pureness. I feel the same way about the RX100 too... is this Nikon bigger than the RX100?
