Sometimes using a wireless mouse is nice. You don’t have to worry about the reach of the cord, or it getting all tangled up in your bag. The only problem is that you may not always have the surface area to use one. A wireless mouse still needs a flat surface, and plenty of it if you actually want to travel across your screen. As this is not always possible, you may want to look into getting the Genius Wireless Ring Mouse.
This will comfortably slide onto your pointer finger, and let you control the workings on the screen with your thumb. There is a touch panel area that will provide cursor movement, and a right and left button for all the clickables on screen. Using a USB charger, you can charge the built in Li-ion battery from either a laptop or PC. With a movement sensitivity of 1000dpi, and a carrying case for only $69.99, you’ll wonder why you ever dealt with a �land-mouse� in the first place.
