I got a coupon in the mail for a free mouse at a Sony store. Since I was passing by the Stanford Shopping Center, I redeemed mine. I wanted a black one to match my laptop, but they only had white and pink ones left. LOL So I got a white one. It works great! Also, not sure what light it uses for tracking... There is no red light shining from the bottom, so I thought it would be infrared, but after pointing a camera at it, it didn't see any infrared light either. o_O What does it use for tracking? Weird.
