The point is with the new IPP, the keyboard Folio is a combination back case cover AND a keyboard. The old keyboard was just a folding keyboard that doubled as a FRONT cover when not in use, or could be folded back behind the iPad when using it in tablet-only mode. But many users, myself included, bought a separate “back cover” that still had one side cut away to attach the apple keyboard/front cover combo. That way, you could remove the keyboard entirely if you wanted, or fold it back, but the tablet itself remained protected in it’s own back cover.
With the new keyboard folio...you can fold the keyboard back, but if you want to use the tablet by itself, then you basically have to pull the tablet out of the folio cover (it attaches via 3 magnets) and then insert it inside it’s own protective 3rd party case. Then reverse process when you want to use the keyboard again, since it won’t fit back into the folio unless naked.
It’s actually a downgrade from Apple for those who don’t want to always use the device with keyboard attached.
OP, I think we are stuck with this bad design decision until/unless third parties come out with their own keyboard/back case combo’s. I’m equally missing the built-in pencil holder I had on my old back case. This magnetic attachment works great for charging, but it’s not strong enough to hold the pencil during everyday use. It’s become detached (accidentally) multiple times now, ending up on the floor.
