Use an iPad. For the price of a duo you can purchase an iPad Air and an iPhone, even more screens, you can run even more apps next to each other. And the iPad can extend its screen to a normal display if you want to run even more apps.

Yea but, a foldable is way more portable and I'll have it with me always. It will be a nice mobile productivity boost for me.

But once you add the price of cargo pants it's a wash tho.
