I hadn't even planned on buying an OM-D (never had an Olympus - my current cameras were Sony A77 dSLR, GF1, and GH2) but, while visiting Boston for the Tall Ships July Fourth event in late June and July, I wandered into a photo shop and saw a black one on the shelf. After handling it a bit, I bought it. After two days of use, I went back to the shop to get a grip and 100-300 lens, and saw that they had just received the silver ones with the 12-50 lens. Bought one of those, too.
Like you, I have always tried to carry two bodies; in the film days it was for being able to have color and B&W capabilities at the same time. Now, these new cameras are so light, that I could carry the two bodies - the grip is always on the black one - 14mm 2.5, small flash, 45-175, 45 1.8, 9-18, and the 12-50. The kit (14-42) that came with the black body has never been used and it will be ebayed as soon as the value climbs above $15! In a small Domke satchel, this kit is very portable...even if I lug along the 100-300, it's not bad. Now that the OM-D has brought the stills capabilities up almost to the level of my dSLR - for all practical purposes for my photography, anyway, I think that I'll dump the Sony system and perhaps even the GH2, although it may make more sense to keep the latter for video reasons unless the eBay price goes up (due to some not wanting the larger GH3).
Portability (size and lightness) is such an issue with me that I've taken the 75 1.8 off my "next lens" list, and may instead go for the much lighter new 60mm 2.8, if the reviews show that it's good for portraits. Of course, we both know if I see a good deal on one in a shop, I'll probably grab it. By shopping at an airport duty-free, I saved $100 (off B&H price) on my 9-18, and I'll be heading to that airport again in about three or four months. That particular airport had a great selection of m4/3 stuff, including all of the OM-Ds and accessories.
Also, like you, I like the same menus and buttons on both cameras that I carry, which is why I chose to buy the second OM-D instead of carrying the GH2, although it does accept both lenses.
My new system got tested two days ago on a hike on the Great Wall near Beijing and it proved to be so comfortable. One body was often in the bag, but sometimes I had both around my neck. I started out with the 9-18 on one body and the 12-50 on the black one (as the lens is heavier and longer) with the grip. Later, when shooting some friends from a distance, I replaced the 9-18 with the 45-175. Very, very convenient. I missed the 100-300, which I hadn't anticipating needing, but everything else was perfect.
Probably the nicest experience was watching the hundreds of people with dSLRs, some with multiple lenses, struggling up and down steep steps, etc., and I had two OM-Ds dangling from my neck which I barely knew were there. And, I'm in geezerhood so every less once counts!
I picked up a 600R flash to get the wireless capability I enjoy with my Sony, and hopefully it will work with my Nissin Di466 - haven't tried it yet. Regardless, I think I'm also going to get the 300R as a more powerful, but still small, travel flash. That will also help if the Nissin doesn't work wirelessly with the OM-D.
By the way, for anyone who's read this far and wondering why some fool would buy two bodies, another reason for me was, in selling my (almost never used now) Sony system, I will more than pay for the 2 OM-Ds, plus flashes, and a couple more lenses. That's even more true if I dump the GH2 as well.
Logic aside, I just really, really liked the camera - it just felt and performed right; prior to that I had had a frustrating experience with stills on the GH2 - a lot of PP, etc., which is one reason I kept the Sony. Another reason was less shallow DOF ability with m4/3. However, the 45mm, 75mm (and presumably the 60mm) have improved that situation. So, perhaps the real reason was that I just wanted another one and the logic to explain the purchase could be developed later. It certainly, certainly, had nothing to do with the couple of drinks I had on a sloop watching the USS Constitution sortie on a beautiful July 4th with Blue Angels flying overhead, directly before calling the store and leaving a message that I would be there when they open to get a silver one! Having another drink after the call (or it might have been email) only confirmed the wisdom of the purchase.
