Does anyone have a detachable keyboard/case for iPad Air/Pro 10.5 that they can use well on airplane tray tables? I am upgrading from an Air 2 with a Logitech Block case/keyboard and I usually have to balance they keyboard off the front of the table to have enough room for the kickstand on the back. it works OK, but I think part of that is the bulkiness of the Block case. I don't care about the size/shape/color so much as I would like something than I can use on a plane for typing, but pull the keyboard off for tableting. Considering the Logitech Slim Combo or the ASK + a backing case, but open to anything.
