Fantastic. I just tried calling the Google Store to ask my question about Google Home. Understandably, the 1st tier person didn't know the answer, and put me on hold to go get it. 30 minutes later the call dropped.

Fantastic.

*edit*

I called them back and got the scoop. No, Google Home only works with one account at a time. It'll respond to anyone's voice for questions, but it'll only give you account-related abilities for one user, which is a bummer. I'd love to be able to tell it to add things to my shopping list, but it would be weird if my wife couldn't do the same to hers. Or even worse, I guess if she tried it, it would add things to my list. That's weird. And I have to assume that when someone other than me asked about their upcoming day, it would give them MY appointments, which seems a little sketchy...
