after much searching i finally found a cigar box which was just the right size (*just* ; if the ebookwise were 1mm larger it wouldn't fit), and i added some foam to the inside for extra protection.
i use this for carrying it around sometimes just to be sure, because i am a bit paranoid ; however, i think that the ebookwise is sturdy enough that if you make sure to protect the screen (like by placing it against a notebook or something) and don't hurl your bag to the ground and jump up and down on it it's probably okay. however i would be careful to protect the screen ; that is the most vulnerable part, i think.
if you *do* find a hard case which is better than a cigar case i think i'd be interested.
