I just received the Incase Origami Sleeve for my iPad 3. I really like my Incase MacBook Air Sleeve, but not the Origami Sleeve. The hard back and plastic is not for me. What I do like is the sleeve does not have a zipper. Are their any other sleeves that are similar to this without a zipper. I dont care if it folds to be used as a stand. I just want added protection when I travel.
