Query: Very nice ergo contraption

This is the greatest thing since swiss cheese for making it comfortable to use a laptop for long lengths of time. Perfect for saving neck muscles and relieving back strain. Love That! But the paper holder is useless. Why would you put a paper holder right in front of your screen and keys?? Strange. But the holder is strong and safe, and I'd buy again.
