I have tested several of the BlueTrack mice since the tech launched and they are very nice rodents. Microsoft has unveiled a new line of mice using BlueTrack that bring the tech to lower price points. The new products include the Wireless Mobile Mouse 3500, Wireless Mouse 2000, and the Comfort Mouse 4500.
The 3500 uses a nano transceiver only sticking out of your machine a centimeter. The 2000 has a larger minitranceiver that snaps onto the mouse bottom for travel. Both are ambidextrous and the 2000 is a full size mouse while the 3500 is sized for portability. The Comfort Mouse 4500 is the first wired mouse from Microsoft to use BlueTrack tech. This may be the perfect mouse for a desktop user not minding wires. The Wireless Mouse 2000 will sell for $29.95, the Comfort Mouse 4500 will sell for $24.95, and the Wireless Mobile Mouse 3500 will sell for $29.95. The 3500 will ship in April with the other two shipping in March.
