I need a solid case to protect my iPad Mini. As an electrician I take the Mini into houses in order to give prices and do billing as well as reference documentation. I like using a naked iPad, but my hands get very dirty and I need to be able to put the iPad down on dirty spots and put it in the side of my tool tray where a naked iPad might get scratched up. So I would like a case to protect it while still allowing it to keep it's really sleek size. Any ideas?
