Wireless mouse with wired pad--why?
Works without battery, but only with USB pad

We'll be honest: This mouse caught our attention because it looked as if it came with its own bodyboard. And, in fact, it does.
That's because this wireless optical mouse operates without a battery--and it needs its special pad to work. The NB-57D mouse, made by A4Tech for the Korean brand Royche, draws its power through an "electromagnetic induction technology" from the USB-connected pad. But, as ingenious as this may sound, we have to ask: What's the point of having a wireless mouse if it can work only with a corded pad?
