Nice idea, though...
Gives me some thoughts for a home DIY project. Something a bit more compact, more portable, take up less room in my bag... hmmmmm.... just a slot to hold the reader and an arm to hold it up.
Maybe a slot made from Kydex, a heat-moldable plastic, (gotta borrow my wife's hair drier again) attached with a pivot (so it will fold and fit into my pack) to an narrower arm to support the weight. "T" shaped. Arm can be 5 inches of plastic channel used for hiding electric cords along the baseboard. That should be more than rigid enough to support the weight of the reader. This sounds like a 15 minute project. Maybe 20 if I round off the edges and make it look pretty.
Damn! I really needed something to fill the afternoon! Maybe give some thoughts to developing a reader with a 'Heads Up' display!

Maybe I should just sit down and read a good book!
