I have to say the Ninja is that for me too, not quite an otaku board, but still smooth keycaps.
Ah, thanks Rip, that is interesting. I was going to mention that I seem to remember the MJ1 had quite a bit of flex in it, but the Ninja is rather inflexible. I'll get some pro pictures and weigh it when I get home. I don't have the MJ1 anymore, so I can't weigh both. I will buy more keyboards.
As far as keycaps, this one seems to be a hunny, all the keycaps are nice and smooth. The extra Win keys are pretty good, though ever so slightly rougher texture.
