Is the mouse you are using today much different from the one you used 20 years ago? Maybe it is wireless but I'm not convinced that mice for the masses have changed that much. One company at the forefront of mouse development is 3Dconnexion. At SEU15 you can try out their new CadMouse and maybe win one in the Solid Edge Design Challenge.
The CadMouse is a new “regular” mouse that is specifically designed for CAD professionals and can be used together with the SpaceMouse (below) for a highly productive 2 handed workflow. The CadMouse has a full size, dedicated middle mouse button so you don’t have to press the scroll wheel hundreds or thousands of times per day. Check out my new blog "Of mice and menus" for a brief history of the computer mouse and to watch a video about the CadMouse.
