I hate wired mice. The wire always seems to create drag as I move the mouse around.
Because I actually really like touchpads (when they are properly set up for me) I've never tried a Bluetooth mouse. I think it would be my first choice though, if you can get one that doesn't use a USB adapter, which would sort of defeat the object. A wireless mouse works very accurately (something that might be an issue with Bluetooth?) but you have the wired receiver taking up desk space, which makes it less practical for laptops.
