Oly OM-D E-M5: What's quirky about it?

Having used my OMD for about 6 months now, it's really down on the quirky list.  For me, quirkiness is mostly being unfamiliar with the camera's functions and also one's photographic goals  (the more I want to shoot everything, the more every camera becomes more quirky).  Now that my goals are more concise I can focus only on the functions that I need (the fewer the better, for me anyway).  So the OMD is brilliant becos I'm more sure of what I want/need with it and realize there is no perfect camera.
