Share your experiences with the M5

[sweat100]

This camera intrigues me quite a bit. Is there anyone using it as their main camera instead of other M cameras? What are your experiences and feelings towards it? I am trying to understand what did the designers at that time have in mind for this camera in terms of handling and usage that cause them to depart greatly from the standard design. I believe it is more than the TTL meter that cause such a dramatic change.
