Microsoft Wireless Mobile Mouse 4000 MS BlueTrack Travel Mouse for Notebooks/Laptops

If you're looking for a new or replacement mouse for use with your
notebook, laptop or netbook (no, I just cannot get on with trackpads
either) you may be interested in the new Microsoft Wireless Mobile Mouse
4000 which employs BlueTrack tracking technology - ensuring precise
tracking regardless of the surface its used on.
The new Microsoft Wireless Mobile Mouse 4000 utilises 2.4GHz wireless
technology and boasts MS's Nano USB transceiver that measures in at a
mere 0.4 when plugged into a USB port, meaning you can keep the
transceiver plugging it whilst on the move without fearing damage. Not
only that, but should you wish to remove the Nano USB transceiver its
nice to know that it'll fit neatly in a dedicated compartment contained
within the mouse itself (meaning it's harder to mislay/drop down the
back of the sofa/get eaten by Fido the Wonderdog, etc).

Offering a range of up to 15 feet, and sporting a button designed
specifically for use with Windows 7 (activates Windows Flip) the
BlueTrack touting Microsoft Wireless Mobile Mouse 4000 will become
available in a host of fashion colors from August when it'll retain at
around $40 a pop.
