im thinking of getting the BT Mighty Mouse to replace my BT Kensington PilotMouse, because my rechargable batteries dont fit properly; they arent making a connection, so it doesnt work. I can use non-rechargables, but thats pretty costly. There isnt a lot of competition for bluetooth mice (mouses?), and Apples current offering seems to be pretty attractive. So would it be worth it to get a BlueTooth Might Mouse? Have you had any problems with yours?
