More and more people are choosing to "cut the cord" when it comes to their choice of computer mouse. Wireless mice are becoming increasingly standard in the computer world, and for good reason. They are typically easier to use, more convenient, and less of a hassle than the wired variety. They do have one drawback, though - they've always required batteries - until now...
A4 Tech's Battery Free wireless mouse with "smart" mouse pad
A company by the name of A4 Tech has produced the Battery Free Wireless optical mouse, which like the name implies, never needs batteries to power it. Instead of batteries, the Battery Free mouse uses electromagnetic induction technology to power the mouse via the included "smart" mouse pad. This special mouse pad is connected to the computer's USB port, and it works to power the mouse without the need for batteries.
This mouse has some other good features as well, such as a zoom in/out button, vertical/horizontal scroll button, and a customizable button. This wireless optical mouse comes with a 1 year warranty and is available for $29.99. Not a bad deal if you consider that it will probably come close to paying itself off in battery savings within two or three years. I also like the fact that you don't have to turn the mouse off when you're done with it in order to save the battery life, like I have to do with my current wireless mouse (man...I gotta get me one of these!).
