Yes, of course. How can I leave a note for somebody in the living room, or pin it to the fridge if it’s on my PC?
How can I scribble my plans and measurements down quickly without endangering my fancy expensive phone while I’m woodworking? Not to mention I need two hands and need to unlock the phone and find the application etc etc, or I could just pick up the pencil.
And what about my shopping list? Am I going to absent mindedly carry my phone in one hand while I push the trolley and pick up food, basically BEGGING somebody to come and snatch it from my hand and run off with it? Hell no. I use a written shopping list.
These are just some random examples, and I do use my tech to note some things down, most notably if I’m sat at the pc and it’s a tech thing I’ll probably load Notepad++ and save a quick .txt note, I have a lot of those. But for little around the house/going out things, my notepaper is always best :-)
