A new product listing has listed a Microsoft Arc Touch Mouse for $70. So of course rumors of Microsoft working on a rival to Apple’s Magic Mouse have begun. The prototype pictured above comes with a similar arc-shape to the current folding Arc mouse from Microsoft.
Curved transparent plastic and frustrated total internal reflection (FTIR) will be used to track several points of contact. And remember, touch/multitouch is already natively included in Windows 7, so a mouse like this would compliment it.
