One thing I'm definitely looking for is for the case to sport a nice, professional look.
A brown leather case would be pretty fantastic, or just your basic black. If the exterior had text saying Adam by Notion Ink or something, that would be cool too. I'm looking for a simple case, that covers all my hard edges, exposes all (or most) of the ports, and something that I can bring into a meeting at work, or with clients. The Adam is definitely one of the more high end looking tablets, sporting a different design and a unique UI, I want my case to show off that I own an Adam, even when it's not open and my Adam isn't out.
