new toy!

I've now got a vertical mouse at work, so far it's great, slides around easily and feels very comfortable.  Words of wisdom from an expert "takes an ordinary scroll mouse and turns it on its side, untwisting the user’s wrist from its standard position into a natural “handshake” posture. At the same time, this enables the weight of the hand to rest on its sturdy side, instead of being painfully piled on the wrist".
