Hi octoberdana, this is a precious piece of information to have. I appreciate it
I'm completely with you about the wish for a cover to be the thinnest possible. An easel is a nice feature to have and I guess my "critical to quality" criteria are a secure non-wobbly mounting/locking system and the most unobtrusive shell I can find and third a cover that is impervious to fingerprints and stains (I extensively use hand cream all day long).
