WinRumors posted a review on the Microsoft Touch Mouse for Windows 7

Microsoft has paid close attention to the design of the Touch Mouse. The mouse features rounded soft corners and a comfortable slope to rest your hand and wrist on. The surface of the mouse is made of matte plastic and features rows of raised dots and x’s. The rows outline the multitouch parts of the mouse surface. The bottom of the mouse features a shiny white plastic surface with quick access to the two AA batteries for the device. Microsoft has also created an area inside the bottom of the mouse to house the USB transceiver, presumably aimed at laptop users. Microsoft also ships a USB extension cable as part of the package to minimise any potential interference.

Microsoft has designed the mouse for ambidextrous use. Both left and right-handed users can operate it with ease. The mouse fits either hand comfortably. The Touch Mouse also features BlueTrack technology. The technology enables smooth tracking on most surfaces apart from clear glass or mirrors.
