I can't practically carry around two different phones all day at work, especially given how big they are now. (It's not like I work at a desk, I'm constantly running between different classrooms and other spaces.) The "work" phone would end up being the one I had on my person most of the time.

...but frankly, I am such a geek that it doesn't really matter for me. I have a tiny 11-inch laptop that I usually keep somewhere nearby, or I can VNC into my home desktop computer from my phone.

The thing is that normal people shouldn't have to do this! I say this as someone who does believe that everyone should become more tech-literate and capable with computers. One of the subjects I teach is 5th grade computer science. I don't expect all or even most of my kids to become professional software engineers, but I want them to know enough that they'll be able to make computers work for them instead of the other way around. This is one of the reasons I became a teacher.

I don't expect all of my students to buy and carry around multiple phones in order to protect democracy.
