I now have my E-P1 white body, which I think is way cool. We went out to a festival in a nearby river town today, and I found the neck strap easy to wear, and I rather like being able to display the camera since it is so great looking. However it didn't work for shooting. Since I was not using the viewfinder, I found that every time I wanted to shoot something I had to remove the neck strap in order hold the camera out far enough to see the screen. It would be perfect for viewfinder shooting, but I find I liked shooting from the LCD. I believe I actually take more pictures than I would with a viewfinder for some reason.
What to do now? With my big 5D I carry it in a small shoulder bag (Lowepro TLZ-1, I think), and then hold it with an RRS hand strap which allows me to relax my grip and let the camera hang on my lowered hand.
Since it really isn't small enough for a shirt or pants pocket, I'm thinking of trying a wrist strap if I can find one I like.
Are there others who spend their energy mulling this over?
