So far, I couldn't be happier with the OM-D. A common knock that I found to be overstated is confusing menu's and user interface. Any new camera system has a learning curve and the Olympus camera is no exception. I migrated from Canon to Leica to Fuji and now Olympus. The point here is I held off buying the OM-D because I got hooked on Leica's simplicity. Still much to learn but if you are on the fence on buying an OM-D, the user interface issues shouldn't deter your decision.
