So does this mouse have issues pairing with Mac OS X after a reboot, or do I just have a faulty unit? I also have the Logitech BT Travel mouse, have tested it on both my MB and MBP, and it's discovered fine after a reboot. The Kensington has to be re-paired on both laptops after rebooting, and this was under both Tiger and Leopard. I'm hoping it's just a faulty unit, because I really like the feel of this mouse. The grip, and the acceleration feel really good to me. But I don't leave my laptops on, and tend to boot up several times a day, and this constant re-pairing is the biggest pain ever. Anyone use the Kensington? The full name is the Kensington PilotMouse Bluetooth Optical Mini.
