For those who require an extremely high level of protection for their iPad or similarly-sized tablet, there's the Extreme Portfolio for iPad & 10" Tablets (Yellow) from G-Form. Once inside, your tablet will benefit from a high level of impact protection against drops and falls thanks to RPT (Reactive Protection Technology) -- a composite blend of PORON XRD material and proprietary G-Form materials and technology.
This lightweight, water-resistant portfolio case has an internal layer of polycarbonate. It also has an inside pocket for safe keeping of documents when you're on the move. When you open up the case, you can use it in several configurations for flexibility. The front cover can be reverse-zipped behind your computer so that you'll benefit from two layers of RPT protection. In this position, the front screen is still protected by RPT corners that hold it in place. Plus, you can use the Extreme Portfolio in an easel or A-frame configuration in either portrait or landscape mode. This rugged case is easy-to-clean, durable and resistant to abrasions.
