Najinsky: Did you get a chance to tell if the buffering and/or write time issues are resolved or improved?
As a raw shooter, it's the most serious flaw of the NX200 in my eyes, and one that puts me right off the camera.
I've previously shot with cameras with poor/slow buffering and writes, and while I was initially patient, it began to get very annoying as one misses more and more moments.
The GF3 implementation is exemplary and the best I've seen in a small camera (accepted it has fewer megapixels to process).
