Most third party flip covers for the SP4 ALSO cover the back of the device. Which might be great for some people but it makes it impossible or clunky to deploy the kickstand. And also hides the beautiful Magnesium Alloy body or one's custom skins. Added bulk is also not a welcome feature for people who use it as a TabletPC and not as a NotebookPC. So any folio a flip cover that attaches to the surface body the same way Type cover attaches. Or comes off as easily as the type cover. And can be detached and reattached in away that it protects the back when devices is being used as a notebook lying flat on a rough surface. Flipped infront to cover the screen Detached and attached backwards to protect the back. I do not want it to flip backwards because that way the surface touching the table will pick up a all the gunk and deposit it on the Screen when the folio is closed back in to position.
