Take it from the fool who knows: I simply ADORE Nikon, but it goes for the two good things that Nikon makes - (D)SLR cameras and their lenses. Every other thing Nikon produces is either overpriced or worse than competition. Nikon's flash units are overpriced. Nikon's batteries and battery grips are overpriced etc..
Nikon's mirrorless cameras are worse than competition - much smaller sensor, which Nikon tries to "excuse" by claiming their goal is/was to produce the cameras smaller than competition's. Smaller size cameras they are, but their IQ is smaller too. Nikon1 cameras are not smaller enough, in my opinion, to justify the (negative) difference in quality of photos, compared to Olympus PEN system, not to mention Canon's M, Fuji XE/XM and Sony NEX systems...
Bottom line is: 1) get yourself a PEN, models like E-PM2 or E-PL5, if you want it to be SMALL and not too expensive (can be easily put into the raincoat's pocket, kit lens 14-42mm included). With the adapter, it is possible to use Nikon's lenses in manual focus mode - the beautiful thing being in-camera optical stabilization that works even with non-olympus lenses (though the original, kit lens will do in most situations); 2) if you can invest some more $ , go for Fuji's mirrorless APSC sensor models (e.g. X-E1).
