Futurelooks posted a review on the Microsoft Sidewinder Mouse

The Microsoft Sidewinder mouse is made for gamers. It sports features seen in many other so called performance mice, including adjustable weighs, switch on the fly DPI settings, and multiple programmable buttons. The mouse is wired, which is peculiar in this age of wireless…everything. There has been rumblings that this is due to concerns over performance lag experienced in wireless mice by professional gamers. Since Microsoft is quite adamantly trying to target that market - and their followers by proxy - out goes the wireless transmitter in favour of a good ol’ USB cable.
