I don't have much information about this yet, but Microsoft is set to release a new version of its IntelliMouse, dubbed the IntelliMouse Pro. From the looks of it, the new IntelliMouse Pro keeps the curved shape and center scrolling wheel of its predecessor, but adds a padded finger-rest area around the wheel to make it easier to control, for a "new level of comfort and efficiency" to quote the packaging. In honor of the changes, Microsoft is changing the box design for the mouse (as well as for the IntelliMouse Trackball), which is now a bright red color. There isn't any information about the new mouse on the Microsoft home page yet, but if I come across anything, I will pass it along
