Just see what happens for what it is compared against the Olympus XZ-2 and the Q10:-

Well, it tells that the XZ-2 and the MX-1 are actually the same camera inside, as most of the marks are just so close, or just identical! :-o
As to compare with the Q10, the MX-1 actually doesn't have a real edge over that little "crappy" ILDC with a smaller 1/2.3" sensor! ;-)
