I am using the Olympus E-P3 and have a olympus OM-D on order. I shoot a Nikon D700 in DSLR.
I read everything and I mean everything. When it came down to it I enjoyed the way the E-P3 felt in my hands. It feels solid and I took to the retro styling immediately. I was really interested in the X100 or the Leica X1 but felt in the end I needed inter-changeable lenses.I think when the OM-D comes in it will immediately pull me away. I needed something for a trip in a few weeks though and could not wait and did not feel like taking the larger DSLR. i was looking for a camera to go everywhere with me and will enjoy having a smaller body nearby. Many of the lenses are coming into quality also. I looked seriously at the V1, the focus is amazing, but I tend to be a bokeh freak and wanted more DOF than i thought the V1 could provide with its smaller sensor. All of these have shortcomings, but in the end I just enjoyed the updated E-P3 more. The OM-D should be even more enjoyable....mini DSLR esq.
