Well, I bought it for vacation, took the trip, and it has sat at home (as well as all my other cameras) ever since. I am far too busy at work to have two camera systems, especially one as was mentioned earlier that will depreciate as soon as a replacement is announced. That said, it was a 12 day trip, 10 of which on a cruise, and even though I brought my 5D and 7D, they only ever left the ship with me one time. The OMD did great, I put about 4,000 frames on it during the trip, and I have no regrets getting it, but I hate to have it just sitting around costing me money and collecting dust.
If they release an E-M7, or OMDpro or whatever that delivers good action photography performance, and a few high quality tele's like the new Panasonic 150mm (but longer), I could see it entering my kit permenantly. Also, the lenses I chose for the trip I did so for their lightness, compactness, and versatility. If I were keeping it, I would make different lens selections, such as the panalecia 25, oly 12mm, maybe the new 12-35 2.8. Ultimately I primarily bird, so I think I will put the money toward a 1DIV, or something like that, which I can use this winter.
