As a gear-head I change cameras (from different brands) at various times and find I often struggle with the shift in operating differing cameras. There was a time when it would have been no problem, but now I sometimes hesitate during the image making process particularly with "Now, where is that exposure comp dial?"
All the cameras are different after all. If this does not affect you at all, then you are lucky IMO. The delay while not long it sometimes flows on and rushes the process.
The Ricoh GRD affects me the least, and the X100 is also less of an issue but sometimes I have to stop and dig for some setting or wheel on the OM-D or the DP2.
I am interested to hear your experiences on this.
