Yep, I have the original 11" iPad Pro from 2018. It still works flawlessly and would be perfect for this use case. Someone who needs a device for school should buy a used iPad like this, not a new one that would be overpowered for the task and would cost double. Even with the edu discount, it's over $1k with the keyboard case. Why not just buy an MBA at that point?
This has been my reasoning for years and it has been great for that. If I have to leave in the middle of the workday for errand or appointment it’s with me in the Logitech folio case and I have connected computing power in my hands in a form factor that is roughly the size of a moleskine.
