Despite the recent preoccupation over Yahoo!, Microsoft found some time to launch two new mice in its Wireless Laser Mouse series, the Wireless Laser Mouse 6000 and 7000.
Both of these rodents will have 2.4GHz USB receiver, Microsoft HD lasers and Vista buttons. According to Engadget.com Microsoft's new WLM 600 will have a snap-in USB receiver packed inside, which makes it some sort of notebook mouse with the size of a regular mouse. The WLM 7000 will not be that portable since it has rechargeable batteries, and will come with a horizontal charging dock which should recuperate your rodent when it gets low on batteries.
Both mice should be available in March for $50 and $70, respectively.
