Just received my WU-1B and played around a little with it. I could see this little marvel being very useful. But what I can't get over is how tiny it is. Not so much the actual size but rather why on earth didn't Nikon build this right into the body?
Strip away the USB plug and the outer plastic case and the components inside must take up the space of a split pea. Why have a tiny extra device that is so easy to lose and a little awkward to store when it should be built right into a $2K camera?
