forced Microsoft's hand into announcing the fall Zune lineup a day early, but nothing can upstage the pure excitement of the Say Goodbye to Laser campaign -- awww yeah, the BlueTrack mice are official today. The new tracking tech uses a (surprise!) blue beam and wide-angle "specular optics architecture" to work on a wider range of surfaces than traditional optical or laser mice, including granite, marble, and even carpet. The new tech will debut in two new mice: a revised wireless Microsoft Explorer Mouse and that Microsoft Explorer Mini Mouse that we'd already spotted. Both will be available at Best Buy in November for $99 and $79, respectively.
