Actually, the great thing about the new Magic Keyboard is that while you’re sitting (unfortunately) in the back of the plane, and you want to shift from typing to doing something in portrait mode holding it off the case, you can simply pick up the iPad from the case, and use it as is. No need to fold anything over or put the keyboard away. Then when you need to get up to stretch or use the facilities, you simply put it back down on the case and fold it flat to put it away. One thing I have noticed as I’ve effectively stopped using my keyboard folio, is that the iPad Pro (12.9”) is great to hold on to outside a a case, when you’re doing things like watching YouTube or gaming. For me, even though I’ve been using it for more than a year, most of the time it’s been in the keyboard folio, so now that I’m using it more outside the folio, it feels like a new device again.
I’ll also add, given I’m traveling similarly on a weekly basis (or was prior to the pandemic), another benefit of the new keyboard is the backlit keys. That was always a pet peeve of mine, especially for night or early morning flights where I didn’t want the overhead light on but needed at least a bit of light to help my typing.
