Ok, if a bluetooth mouse uses bluetooth... what does a stand wireless mouse use to send the signal to the usb receiver? And why would anybody use the wireless mouse and waste a usb port if their computer has bluetooth? fyi I use the trackpad at the moment (BlackBook) and the mouse I prefer to use doesn't come in a wireless version. If this does come in a wireless version let me know. All i can find is the wireless thumb trackball. And while we're at it which mouse do you use?
