Make sure you get ALL those nits K? Just to be fair. And it doesn't change the "look of the band" does it, since the band is being replaced. It still looks the same band as before, just it's now in a drawer somewhere.
That's the additional revenue stream: accessory bands to easily mix and match. As soon as I saw that band connection system I knew there'd be the possibility of a collection, change the look of the watch by simply slapping on a different band.
Indeed: the online campground reservation system for Yosemite is a classic of that phenomena: the place sells out in a few minutes for the month long blocks they release five months in advance. The park goes so far as to provide a link to the national standards atomic clock widget so you can time the hit of your submission precisely....
The FDA took notice (and IIRC there were meetings between FDA and Apple on the subject reported).http://www.bloomberg.com/news/articles/2015-03-30/fda-taking-a-very-light-touch-on-regulating-the-apple-watch
Another catalyst for Apple Watch sales is the current trend to larger iPhones: all of a sudden a casual phone check involves a much larger, in ways more cumbersome, device, opening a slot for the Apple Watch, especially with the 6 Plus.
Apple (Cook?) noted a similar sentiment in mentioning the Watch as an effort to give people a bit of distance from their iPhones or something to that effect.
