I have not, though there is another thread where they talk about it
here.
I read in a different thread that it looks just like the organizer covers you can buy, in which you can get them for under $10 and cut out a clipboard and insert it in the front for extra protection. (Don't remember where I read it though, so no link)
Me, I (finally) just ordered the
Tuff-Luv cover that they talked about
here. Hands free reading while eating, here I come.
