Killing the goose
I have bought and used Android phones since the Nexus 2 - basically because I was fed up with the other companies continuous efforts to install crap on the phone and up sell me with various services like email access. And then Google introduced the "Play Store" ... my Nexus 6 phone is now stuffed with apps that I do not, and will not, ever use.
I'd switch to another vendor except everyone else is worse ... but my actual voice to voice talk time on the phone is down about 80% over the last 10 years - I'm inclined to think that voice phones, like pagers, may be on their way out.
