There are a lot more, all concepts pre-dating the Microsoft Surface. . . and every one of these are licensed by Apple as an approved product for the iPad. I told you, which for some reason you REFUSED TO BELIEVE, that I threw away a keyboard cover with a kickstand for my original iPad that I no longer had. . . It was in our trash bin until about an hour ago when the waste company emptied it. You just cannot think beyond your Apple hate blinders.
Uh those are cases and they are third party.
