Can you hear me now?

This is one of the weirdest things I've seen in a while. A mouse with a phone built in. All I want to know is, why? From the picture it looks like the back half of the mouse disconnects and has a keypad on it, so there's your phone. You can even talk hands-free with an earphone (waz an earphone?)! Also, I think you'll be asking "Can you hear me now?" a lot on these things. Right now you can't buy it, but they say it will cost the same as a middle priced mouse. If you want to, you can throw a lasso around this link for more info.
