The real problem with anything Google makes that is"new" is this:
The whole concept of "Oh, this is not making us as much money as we had hoped, let's sunset it and replace it with something else!" *really* annoys me.
Google Chat? Nope, now it's..
Google Talk? Nope, now it's..
Google Voice? Nope, now it's..
Google Hangouts? Nope, now it's..
Allo and Duo?
What makes this more then incremental to the latest Nexus, hardware or software wise?
And why does that justify the price jump?
