Face it in towards clip. Will sleep it in either direction, but you'll get more protection for the screen facing in. And depending on your grip, you'll be holding it facing the right orientation for answering/email whatever if you store it this way.
There's a groove on the outside of the OEM case for the 8800 as well (albeit not as long of one). I faced mine out on my OEM case, but have it facing in in my Seido case.
