Well, I got a Roots leather envelope cover. It looks as the name says, like an oversize envelope:

Next time I am in Future Shop I'll see if they have the InvisibleShield, but I think this might be good enough. Especially since my reader's old and everybody else has a better one than me now.
I saw the new touch Kobo and it's a lot smaller than the other kinds. Isn't it too small for the cases?
