Nice comparison of features, although I feel the 'I prefer the 3:2 aspect ratio' one is moot, given you can simply set JPG output (and EVF/screen framing) to 3:2. In fact, I have, because 4:3 aspect ratio just looks like a TV to me. Can't shake it. Do not like.
(i.e. I will be cropping all of my RAW processed shots from the E-M5)
