OP, how do you feel about its sturdiness? I'm thinking about picking one up, but I've seen some posters and a YouTube mention that the keyboard tends to waddle due to how the hinge is on this keyboard model.
This is a far as mine bends without the iPad attached to the Magic Keyboard, when holding the folio like the OP. Note it has not gotten a lot of use. So I do not know if over time it would match what the OP is experiencing.
