Back in the day, looking at your phone constantly was an odd thing to do.
Basically, Blackberry addiction was the first described smartphone addiction. Blackberrys were the smartphones before smartphones, used mostly by professionals to keep their biz in their pocket while away from their desktops (those fat, ugly-looking phones that had a lot of buttons on them).
Blackberry addicts back in the day were considered rude, giving their attention to their phone over people that were right in front of them. Nowadays, it’s not uncommon to see two people mindlessly eating their lunch together while both are completely sucked into their iPhone or Android screen.
What does the future look like? We're sure there's an app that would tell us.
