Microsoft Touch Mouse brings multi-touch
Microsoft's hardware team marked CES by adding a multi-touch mouse. Just known as the Touch Mouse, it relies on a nearly unbroken touch surface to handle many of its commands, like Apple's Magic Mouse. Microsoft's hardware can support two or three fingers for window management and viewing the desktop respectively.
Unlike Apple's implementation, the Touch Mouse can recognize different finger sizes and uses thumb swipes to move back and forward in pages where Apple uses three fingers.
The mouse runs on blue laser tracking and talks to the host computer over RF wireless and a nano USB receiver. Microsoft hasn't given a battery life estimate. Despite the announcement, the company won't have the mouse ready until June, though it already has an official $80 price.
