these camera system is pretty new and not so many users out there.
so if you are one user, you can tell everybody why do anybody want a mirrorless interchangeable/or EVIL/or hybrid/ interchangeable Point and shoot or whatever fancy name you want to call it.
Let's discuss questions like 'Why would one buy it over a point and shoot or over a DSLR?'
what is the future of this system ? how does it stack up on image quality? will it replace DSLRs? For whom is this camera intended? cost, lens... etc etc.
Examples:
Olympus PEN
Sony NEX
Samsung NX
Panasonic G mirrorless
I own one and i'm definitely enjoying the experience with it. (Samsung NX10)
