I know there have been a lot of threads on cases but I have not seen discussion of the smallest case possible. I don't want it to hold cables or keyboard or anything other than the iPad2 with Smart Cover. I want it to be as small as possible. A plus would be for it to have loops for a shoulder strap messenger bag style. I want it to something professional that I will use to carry my iPad2 into meetings and such.
So far the ones I've seen are (EDIT - Added more sleeves from thread and beyond):
SFBags - WaterField Designs - iPad Ultimate SleeveCase - iPad Sleeve - iPad 2 with Smart Cover - TSA Checkpoint Friendly
Vaja - Leather Products
bezyzacases Slim Bag Series
bezyzacases Wave Series Sleeves
Targus Hughes™ Leather Portfolio Slipcase for iPad
