Since there's been some rumors floating around about Apple adding functionality to the Watch via "smart bands"… How do you think they would work? Open the so-called diagnostic port? So, give users a tiny tool to pry it out? Then, make the band one-way only, or make it so either end can plug into the port? And how will the little connector slide through the close-fitting slot in the watch case? How about Bluetooth between the band and the Watch head? Lastly -- has the practicality of AW-connected smart bands been discussed here already and I just missed it?
