Hi, I am looking for a new mouse. It can be optic/laser, probably standard or bigger notebook mouse, bluetooth enabled mouse. I don't want to use that bluetooth dongle (i want to free up one usb), I just want to use my bluetooth in notebook. Do you think I can use the integrated bluetooth receiver even if there is any dongle enclosed with the mouse? I like Microsoft 8000 wireless presenter, but it has a dongle. What other mouse would you recommend me? (Microsoft, Logitech, but NOT Genius).
