I'm waiting for the update to the Zum SC Ultimate, my favorite iPad 2 case to use in combination with the Smart Cover. I looked at the Incipio Feather at the MacMall store here in Chicago today and almost pulled the trigger but the exposure of the top and bottom of the iPad was a deal breaker for me, I'll wait a few more weeks for a Zum.
I just don't like the Zum logo on the back. Wish it was more discrete!
