Has Anyone Tried the Quill Mouse?

Anonymous Coward asks: "Has anyone at Slashdot has heard of or used the Quill Mouse? It's an odd shaped mouse that's supposed to reduce repetitive stress injuries like Carpal Tunnel Syndrome." Rather than grabbing and moving the Quill mouse with your hands, you rest your hand in the Quill's "nook" and move the entire assembly with your arms. Since the palm of your hand is facing inward, you can then click the buttons which have been rotated to match the "nook". The web page says this hand position is less likely to cause RSI than the position a standard mouse requires. Anyone with (or who have used) a Quill Mouse care to comment?
