I tried this approach on my current iPad Pro M1, and I would say that it is really cumbersome. I bought the Logitech Keys 2 Go 2 and thought it’s okay. But the lack of built in trackpad sometimes gets in the way. Unless I dock my iPad and use stage manager solely, it makes much more sense.
Magic Keyboard all the way.

Great read from you again. I enjoy your stories! Keep it up.
