There was a recent article in Luminous Landscape where the photographer decided to go with a M4/3 system for long range photos and a Leica medium format for short range and landscape photos and thought it worked much better. Given his experiences, he argued that hauling, clamping, and constantly connecting was just too much trouble, and that a M4/3 allow far more flexibility and comfort.

What a bunch of complainers on this forum! Have ANY of you even tried the camera yet? It's barely in anybody's hands and practically the whole lot of you (with some exceptions) have dismissed it. How about a parallel? Nobody asked for a minivan 30 years ago and many thought it would die a quick death but it become one of the most useful vehicle configurations ever.
For some of us who travel and value compactness, even a small dSLR is too much. I love my D3s for sports and high impact occasions, but there is a reason why technology is designed for different scenarios. I can see something like the Nikon 1 being very handy.
THINK about it people...
