Personally, I got my first phone when I turned 16, in mid 2015. Before that, I never really saw the point in having one. It was a cheap, low quality budget phone, that got unbearably slow after two years. In 2017, I bought a Samsung Galaxy S7, which I am still using right now. I put the latest LineageOS on it about a year ago, when it turned out a common payment app no longer supported Android 8.0.
In the years after obtaining my first phone, it indeed soon became apparent that everyone and everything expected everyone else to have one. The schools and universities I attended since indeed held Kahoots (the winner often received a free bar of chocolate), and looking something up online on a phone was often required.
Meanwhile, there have also been a few months in which I refused to take my phone with me to school, because teachers could request all students to hand in their phones upon entering class at will (smartphones can be a major distraction, afterall). This has made it harder to do some assignments, sometimes, but I still believe my “protest” was worth it.
Good for you. I’m gleefully hosting both.
