"phone" is a weird word to use for these devices. It's a computer in your pocket with instant access to the Internet that just haphazardly has a GSM module for legacy reasons.
This is even more striking when my kids (3 & 5) ask for my phone: I'm watching a common word get completely changed for the next generation. Adults think "phone" as a verbal communication device, often having been overloaded with a stunning amount of alternate communications & computing power. Young kids see a "phone" as a visual toy and movie player, with data communications, and voice calls relegated to "yeah, you can do that too". "Phone" may very well largely replace "computer".
