Here are my initial thoughts on the OM-D:
-feels nice and solid in the hand specially with the upper part of the handgrip (which I plan to use all the time); For my taste just the right size to feel like a real camera
-with the weather sealing and sturdy built this will be my "outdoor in rough conditions or bad weather camera"
-user interface seems fine to me-even though still too many options and buttons for my personal taste
-nice snappy fast AF
-usefull range of the 12-50 - even though I wish it was slightly faster-and they should have included the hood in the price
-the sound of the ibis...I think I got used to it
-I still had the 20/1.7 from earlier m4/3 time (and my wife still has a gh1) and must say the 20 is a great focal length for my taste. Plus small, plus fast. Could become my favortite lens for the om-d.
-IQ-looks fine so far but I really dont have enough experience yet
