One cool thing is about the mouse’s design is the battery compartment. There is a switch on the bottom that activates a quick-sliding mechanism that opens one side of the wedge to insert a single AA battery (which is included). You can’t latch it again unless the battery is inserted in the right direction.
One thing to keep in mind about the Microsoft Wedge Touch Mouse is it’s compact size. While the size is great in terms of portability, it’s ergonomic design is not the best available. It isn’t comfortable to use if you have large hands. The smaller size may force users to cup their hand more tightly around the mouse. The Wedge Touch Mouse is definitely not meant to be a replacement for a regular desktop mouse.
The Microsoft Wedge Touch Mouse is a great choice for those looking for a simple, easy to use mouse for travel. The only other mouse that I would recommend for people who travel a lot is the Microsoft Arc Touch Mouse (unfortunately it requires a USB transceiver). The Wedge Touch will be the mouse that you want to have in your bag as a compliment to an Ultrabook or tablet running Windows 8.
