Which devices do you use in homeshoololing?

Which electronic devices do you use in homeshoololing? I usually do it like this: B. Mathematics conference (on teams) I run the conference on the laptop and open the book on the iPad. Next to it is my notebook

Cell phone and iPad

MacBook for writing

iPad for conferences and art

Cell phone to write with friends on the side.

PC for conferences and mobile phone for documents when I'm at school.

I can't recommend conferences on the mobile phone (iPhone), it just seems to drain the battery unnecessarily in the long term.
