Nikon's recent introduction of the V1 and J1 cameras has started anew the always interesting, but tiresome, discussion of which mirrorless camera lineup is the best and has the most staying power. To be honest, I really couldn't care one way or another, but some people like to defend their choices at the exclusion of any other choice. I don't find that to be a very productive debate. As I see it, the mirrorless market right now is populated by an array of choices each of which has their own list of advantages and disadvantages. Which of them work for you is purely a matter of personal preference and needs.
For example, my first mirrorless cameras was a Panasonic GF-1, which I bought in November, 2010. I still think it's one of the better cameras in this class ever released and likely will go down as one of the early classics. It combined a durable build, good controls, and came in a package that included the excellent Panasonic 20mm lens. However, I don't own it anymore (a decision I sometimes regret, but that is tangential to this discussion) and that is because one of its disadvantages got in the way of what I personally want from one of these cameras. That's not to say the m4/3 system isn't a great system. In fact, as a system, m4/3 is probably the best mirrorless system out there and if I had to guess which of the systems was likely to stick around then it would be my current pick. So if the system was top-notch then why did I switch? Well, what I didn't like about it was the 2x crop factor. I like to shoot manual, adapted lenses (the reasons why this is so might make for another good topic to write about) and the 2x crop factor made every lens I tried just a bit too long for my taste: a 28mm became an equivalent 56mm and a 50mm became a 100mm. Even my ultra wide 15mm turned into a rather average-wide 30mm equivalent lens. It was for this reason that I began to look at the NEX system. The NEX, along with Ricoh's GXR and Samsung's NX camera, offers an APS-C size sensor, which gives me a 1.5 crop factor. My 28mm become a 42, the 15 becomes a 22.5, and the 50 becomes a 75. Those focal lengths felt better to me, more useful.

I no longer own a 50mm lens as I've sold all my adapted SLR lenses and I'm slowly replacing them with rangefinder lenses, but the above two lenses make a pretty good two lens kit.
Anyway, I haven't made my point which is for each mirrorless system available there will be someone who doesn't like it for everyone someone who does. Someone will find great use with it while another will not. To each their own as they say. Remember the point is not to defend your camera of choice; the point is to find one you like using and to use it.
