Its a subjective thing. While i am seeking something that isn't as cumbersome as a 5dII i felt that it was too small for my hands which are quite big. If i wanted a 'small camera' i'd just get a P&S. My nikon FM2 is the perfect size for me. But film is a big burden!
Im not looking for something to shove in my pocket, just something i can leave on my desk and grab whenever i go anywhere.
i told the lady i would come back in when they had a demo grip. I took some samples on my SD card though and the IQ was really good!
For most M43 users though, a P&S just doesn't offer the control or IQ. Even a Canon GX(X) series doesn't offer interchangeable lenses and has a smaller sensor.
