Well first of all it's a bit more than that. I mean it has the built in induction charging of course. And secondly...
This is the killer. No one knows what the final price of the watch will be but the edition collection will likely be in the thousands. A $60-$80 accessory for your $3,000 watch doesn't sound too crazy (Yes, to many people a $3,000 watch sounds crazy, but that's another story).
If and when I ever get an Apple watch, I think I would prefer to have some sort of a display stand/dock like this. I'm sure many different kinds/styles will be released.
