Although I feel that the Samsung NX10 menu system is much, much better than the Sony NEX3 menu system, the image comparison of the two cameras at ISO 1600 convince me that the Sony beats the Samsung where it matters most - image quality. And the extremely high ISO ability of the NEX3 is another area where I know I will appreciate the NEX -- parties in dark rooms are the bane of photography, and the NEX will surely be the best there.
Scroll down to the NEX vs NX10 image on this page:
I'd like to see a few more YouTube videos of the NEX menus to reassure me a bit more than they can be learned, but, ultimately it looks like I'll be getting the NEX3.
Haven't decided on silver or black, or 16mm or 18-55mm. I'm leaning towards silver body and 16mm, especially after Cnet trashed the 18-55mm lens. Plus I imagine the lack of shake correction on the 16mm will help save the battery.
And ultimately, the NEX3 with a 16mm lens looks like it won't intimidate anyone who I am photographing. It looks so innocuous.
