Microsoft unveiled its BlueTrack technology a long time ago. The tech helps a mouse to track better no matter the surface and it works pretty darn well. The tech has been used in wireless mice that are typically expensive until now.
Microsoft has unveiled a new line of mice using BlueTrack that includes the Wireless Mobile Mouse 3500, Wireless Mouse 2000, and the Comfort Mouse 4500. The 3500 and 2000 are both cordless mice with ambidextrous designs. The 3500 is sized for notebook users and the 2000 is a full-size desktop mouse.
The 4500 is the first wired mouse to use BlueTrack technology. The 4500 and 2000 will ship in April for $29.95 and $24.95 respectively. The 3500 will ship in April for $29.95. The mice can be pre-ordered on Amazon now.
