The biggest problem with the Pixel phones, and it's almost like Google don't WANT it to succeed, is the price. If they really wanted to disrupt things they would've made it for barely any profit knowing they'd reap the extra cash from ads and data collection. They just don't seem serious.
As for Home: Siri, Cortana, Alexa, Eve, Samatha - these are all names you wouldn't be TOO embarrassed to be seen talking to. "Okay Google" is a name you would. They need to introduce some personality into it, let people name their assistant what they want. This dead eyed corporate Okay Google nonsense is going to get them nowhere.
