As cell phone data speeds have improved, may young folks are gaming on their phones, watching videos on their phones, texting, accessing the Internet, e-mail, or whatever - all on their phones. The only thing they are not doing is talking on them. And since a smart phone can be used as a WiFi hotspot, you can even log into your e-mail from your laptop, using your smart phone as an internet portal.
It must have a removable battery, too - and a reasonable battery life. Not too much to ask, right?
