content: A Nexus 5x 16 is $379 normally, got mine at $329. An iPhone 6S is $649, so we can call it two Nexus phones. Beyond that, the phone support angle is a cost too. If they have people on the older OS, they have to have their people trained on how to do things on each version. Not to mention security issues. I think people will claim this all the time, even with security updates.
