The pink mouse will retail until the end of September 2011 for $40 and contribute 10 percent, or a $4 donation, per sale to the Komen for the Cure charitable fund. The non-pink versions all sell for $40 as well, so Microsoft isn't making any extra profit with the pink price tag.
The Wireless Mobile Mouse 4000 features Microsoft's BlueTrack Technology, which "combines the power of optical with the precision of laser" to work on virtually any surface. The 2.4 GHz mouse also has Microsoft's Nano transceiver that sticks out less than a centimeter from the USB port but still gives you up to a 30-foot range. Microsoft estimates the battery life at 10 months and of course the battery status indicator will warn you when battery power is low. The mouse also includes a button for Windows Flip in Windows 7, four-way scrolling, four customizable buttons, and comes with Microsoft's worldwide three-year limited hardware warranty.
