Thank you, for this useful comparison iPad case video. Have owned for several years, the basic 9th generation iPad which, is fully maxed out with 256GB and the cell data option. The case that, I decided to buy is the Logitech Combo Touch. This model connects by using the smart connector on the side of the iPad (so, no blue-tooth is needed), its keyboard has a "back light", it has a pencil holder for Apple's 1st generation pencil, and its Logitech app receives software updates when Apple makes a change to the iPad operating system (smile...smile).
