That's the first I've seen that mouse in the post, might have to track it down... There are a few different vertical mice on the market though. I give them an enthusiastic thumbs up. I personally use the Evoluent Vertical Mouse. I used to suffer from chronic pain in my mousing arm and wrist. I noticed an immediate difference the day I switched mice. Not to sound too much like an infomercial, but it really was incredible how quickly switching mice fixed my pain.
