I always liked OVF, but failing eyesight led me to try the M240 (sold the M9) with its 2.36 EVF. Many complained about tunnel vision and the like while using that EVF, but I never found it a problem for me. This could be that I use what I have in my hand and as such never concentrated on the EVF's limitations, but just got on with the task at hand with the tool in my hand.
To me the histogram in the VF is crucial for me in digital work and EVF's with that feature are terrific to have since for me it initially minimized chimping and now all but eliminates its need in many situations.
Often when I see other photographers chimping after each shot with an EVF, it reminds me of what I see on an airplane where nearly the entire plane load of passengers, while waiting to disembark the plane, automatically pull out their cell phones to look for messages or what not. Of course once the phones reconnect on the ground most are getting some form of vibration or audio ping telling them to look at the phone, but it's always is an interesting observation these days. I actually liked the days when no phone was present in the field and the idea of talking on the phone was the furthest thing from my mind when in the zone of image capture. Guess I'm showing my age now.
