I have the same setup, it works well, been doing this for years now. I like to be outside as much as I can and for that reason I like having 20 hour battery life (good phone with an external battery). My setup fits in my pants pocket and usbc chargers are everywhere (bars, restaurants, hotel lobbies, everyone has then at home) if you don't need to charge a laptop with them. Where I live is a lot of sun and seeing your laptop screen even in the shade is hard; no problem with this.
The issue with the top and bottom edges and the too low res are the only downsides; both will be fixed as time passes and the inconvenience beats lugging a laptop and charger around and finding outlets instead of literally never needing any except while sleeping.
