Quick summary for anyone looking at these cases. http://www.spigen.com/tablets/apple/ipad-mini/ipad-mini-hardbook-case.html http://shop.portenzo.com/hardback-for-ipad-mini http://www.dodocase.com/products/hardcover-classic-for-ipad-mini-cases All three are the same physical size. All three are nearly the same weight. The Portenzo and Dodocase are nicely handmade with different material options; the Spigen is more manufactured, using a light rubber material for the outside and a fabric on the inside. Portenzo and Dodocase use adhesive; the Spigen uses a matte plastic frame. They all have "HARD" in their names. Portenzo and Dodocase are proper folios with minimal stand-ability; the Spigen has a rubber nub that lets it stand. All three let you wrap the cover around the back, book style. In the end, I have to give the thumbs-up to the Spigen Hardbook. It looks like a book, and what it lacks in the "wow this is a nice homemade book cover" department, it makes up for in functionality - that is, the ability to act as a decent stand.
