For note taking, I prefer pen and paper. For diagramming and brainstorming, I prefer a physical whiteboard. For non-work related scheduling, I prefer marking things on the physical calendar hanging on my wall... or sometimes I'll reach for a post-it note.
For bills, I prefer that my company mail me a paper bill. Especially if accessing the e-bill requires me to have an account with a web app and enable MFA and change my password every 90 days and always have Okta give me problems when I want to check my bill and thus need to jump through these hoops those whopping 12 times per year that I need this information.
Maybe it's because I see how the sausage is made. Maybe it's because I use some sort of eletronic device all day for work. But the last thing I want to do when I need to jot something down quickly is reach for a phone or a laptop. Heck, most of the time I don't even remember (or care) where I left my phone.
