I have a 2018 12.9” iPad pro. Since the latest iPadOS update, I’ve been using my trackpad, which works very well. I’m typing on a 7 oz jelly comb foldable keyboard and use a muse case. I think this arrangement (portable keyboard, Apple trackpad) is better than the new magic keyboard will be, as the iPad is free and doesn’t have to be taken out of its case if I want to use it without a keyboard/mouse. It seems to work extremely well, and the keyboard only costs $27. Also, the keyboard can be used with almost any computer or tablet.
