Haven't seen anyone else post it but I obviously haven't seen every post so I'm sure some one has..... but I think it would be a good idea for apple to sell the watch and bands separately..... but hey, guess those guys at apple are way smarter than I.
Apple knows that they can't manage shipping and stocking all of the different bands or predicting which band will be the most popular and overstocking that one. I'd imagine that you'll see a bandless option sometime in the future but not just yet.
