So I'm thinking about getting the padtab system to mount my iPad to my walls and cabinets. The issue is I don't want to stick an attachment directly to my iPad. I am one who loves the design and feel of the iPad, and I normally don't like cases, but for this, a case may just be the answer. But i need a case that i can easily put on when home, and can easily be removed for when i leave the house. So am I asking the community for your suggestions. I'm looking for a case: - costing 30$ or less - has a smooth, flat back surface - stable/rigid material - can easy be taken off and placed on - a back case only (no screen cover) Note: iPad 3 Thanks in advance!
