Hi all, I'm looking for a keyboard case with the following requirements: 1) an actual case, where I don't have to remove it in order to use it as a keyboard 2) a case that's also a protective case in case of drops and snaps closed 3) ideally I could remove the keyboard when I don't need it to save on weight and use it as a case that will stand and that I can fold back for reading Do any cases fit my requirements? So far the ZaggFolio and Adonit Writer Plus seem closest to what I'm looking for. Are there any others I should look at? Does anyone have the Adonit and like/dislike it? There are very few reviews here and I'm interested in your experiences. Thanks!
