The famous camera. Chatting in the store after the 5th Gens were introduced at CES last February, some 3D buddies and I were wondering if the addition of the camera was what made the 5th gen "worth" so much more money, since the specs didn't seem to make any appreciable improvement. In fact, there some items we can't build on the new one that we can on the old one due to the change in shape of the bed. And we still keep bumping into that darn 150mm Z height limit!
