Cordless vertical mouse?

[Rudbaeck]

I've found a bazillion vertical mice, both the joystick grip as well as the more innovative design of the Evoluent vertical mouse.

But, and this is a big but, is there a cordless version of these? The cord causes extra strain on the wrist, and having a cordless mouse made a world of difference. I want to switch to a vertical mouse (as should all of you online pros if you want to still have use of your right hand in five years) but I can't for the life of me find a cordless vertical mouse!

Someone must have seen one! If so please post a reply. [img]/images/graemlins/smile.gif[/img]
