snaps in (nothing that has anything that wraps around the "frame" please) does not have a magnet that is too strong so that it shuts the iPad off when I'm holding it like a paperback book and this is the one that's hard to describe: again, when holding it like a paperback, I don't want the front flap to "slip." Like maybe something with velcro, a flap, or just something so it fastens to the back and stays in place? preferably $30 or under, but I don't want to sacrifice quality for price, so that's not as important as the first three. Right now I'm using the Griffin IntelliCase and I love the looks of it but the only criteria it meets for me is the first one. I've spent several hours on Amazon looking for something and I just can't make a decision. TIA!
