I wish somebody would figure out a way to get the Smart Keyboard Folio working with the 13" M4 iPad Pros.
I bought one with the Magic Keyboard and returned it. The MK makes it into a laptop and that's not really what I want. The folio is perfect for me. It doesn't add much bulk, it can fold all the way around to be flat, it's easy to remove, and is nice to type on (IMHO).
So I'm back to using my well loved 2018 iPad Pro with the Smart Keyboard Folio. It's my favorite computer to work on. Not sure what I'm going to do when it finally dies. I don't think I'll have many options aside from giving in and getting a Magic Keyboard. To me, it seems to be the least worst option.
