If you didn't get enough wireless mice news the other day, here's a little more. Microsoft just announced the Wireless Mobile Mouse 4000, its newest portable wireless mouse targeted at netbook users. The Mobile Mouse 4000 uses BlueTrack technology, a new advancement which supposedly provides better accuracy than laser and optical mice.
The BlueTrack technology is supposed to perform well on any surface, including uneven surfaces like carpet and unfinished wood. The Plug-And-Go Nano transceiver will only stick out 0.4 inches from your USB port, making it easy for you to plug it in and forget about it. The mouse runs on just one AA battery.
It has a maximum working range of 15 feet, and will be available in August for $40. The Mobile Mouse 4000 comes in five colors, including white, aqua, pink, lime green, and black. Check out the site for more details.
