I'm really starting to dislike you RX1 people

Life's too short.  If you can, buy the RX1.  Like you, I have used many tools.  This past year, used many FF as large as 1DX with a 70-200 to as small as the RX100.  Love them all.  They are always great for something.  Even underwater P&S like the Olympus TG1 is terrific for tasks other than underwater.

You seem like, from your pictures, a guy that will make really good use of a RX1.  You hate the weight of even a (light) A900.  You know deep inside that you no longer want large.  RX1 sounds perfect!

Life's short.  Go for it.....
