Secondly (call me close-minded) I honestly don't get what use/niche 'Smart Watches' fill.
Got a notification? Whip out your phone.
Got a notification and need to respond? Whip out your phone.
Got a notification and need to respond but are 10 meters away from your phone? Sprint like hell to your phone...or conversely, wait till you find your way back to your phone.
Got a notification but don't want to obnoxiously check your phone in front of your significant other/friend/coworker/familymemeber/human? Newsflash: You're still being obnoxious when you check your watch/Glass.
Want to change your music? Come on, your phone lockscreen does that in one button touch too.
Want to check your "team's score"? Google Now. NFL app. Lockscreen changers. Etc.
Want to personalize your watch? Let me link you to a personalized watch store. http://www.amazon.com/Watches-Mens-Womens-Kids-Accessories/b...
Want to have a watch that works underwater? See above link.
Want to customize your watchband? See above above link.
Want to read it in sunlight? ...
Want to wake up (assuming you charge it at some other time) with it's gentle vibrations? Lots of smartphone apps ( and of course Jawbone Up, Nike Fuel Band, FitBit, etc) do that as well.
Want to know the time? Well...Sure.
I just don't really understand the rationale behind smart-watches [as they currently stand].
