I just picked up an M1 MacBook Air and would like to get another iPad to use with Sidecar. I'm wondering how the 5th-gen Mini would be for this purpose. The second screen would be used to display spreadsheets, PDFs, and for streaming audio/video (not all at the same time, obviously). My 10.5-inch Pro works nicely for Sidecar, but if I can get away with a smaller, cheaper iPad, that would be ideal.
