The under-screen camera essentially doesn't matter. For the three times you're in a meeting with it, it'll hold. For everything else, you'll use the primary camera and the front screen.

There's a perfectly good use case of using this device unfolded with their kickstand powered folio case and a portable keyboard — While getting some zoom calls and productivity / work done.

Lots of people use facetime for personal calls rather than zoom meetings.
