That's only because the pixel density of the Nikon 1 is greater than any other interchangable lens camera Nikon makes. Putting a super tele on an EOS M is pointless because the pixel density is the same as the 7D (which is considerably better than the EOS M in almost every single way), 60D, T2i, T3i and T4i.
Pixel density means absolutely nothing other than at 100% it covers a bigger area. The quality of the pixels is so much more important than how many there are.
I completely agree with you, but pixel density is the only reason a Nikon 1 has an advantage over other cameras. And the EOS M has no advantages over other Canon cameras.
