After having it on and playing with it for a bit, I find the design and overall execution to be stunning.
To such an extent I think it could be as iconic as the Nathan George Horwitt Museum Watch for smart watches.
While I can't promise I will trade my S6 for a an iPhone 6S in the fall, the Apple Watch is having a some swaying power with me.
Exactly what I would expect. It's an accessory product that makes the ecosystem a stronger competitor overall. Apple's products are more and more about the ecosystem and really not marketed to those who want to be platform agnostic.
