The Microsoft Wireless Mobile Mouse 1850 is very compact, wireless, and suitable for both left and right-handed users. In addition, it's plug and play, so you can use the mouse on any desktop or laptop without having to install it first. You can connect it to your laptop via the included USB nano receiver. Because of the 2.4GHz frequency, you won't get static or interference with other wireless devices. The receiver can stay plugged into your laptop when you're on the road, or you can store it in the mouse.
