If it is actually "smart" in any appreciable sense, I'm interested.
Right now, I see nothing on the market that even approaches anything that would justify using that term. The best that these watches have to offer at this moment is that they're about 3 seconds faster to look at than the smartphone in your pocket. Maybe if you're a lady and keep your smartphone dug in deep in your bag of holding and it takes you a minute of searching to find it that's interesting, but for most people I don't see any actual practical value (not that that would stop a million or so customers from buying it simply because it's new and flashy and advertisement budgets have convinced them it's the second coming).
I can't say what a watch would need to be interesting. If I could, I wouldn't post it here, I would sell it very expensively to Apple. So I'm looking for what everyone announces, maybe someone is smarter than me and I'll say "I didn't think of that, it's really cool". But so far, that hasn't happened.
