There's no reason that an optical mouse has to be wireless. Similarly, there's no reason that a wireless mouse has to be optical. I've used wired (USB) optical mice for ages now and love the fact they they never get sticky. I find that ball mice gum up with detritus and you need to give them a good shove to get the ball to move. Optical mice always respond immediately. As for not working on clear surfaces, consider yourself lucky. Sun optical mice (e.g. http://www.memoryxsun.com/3701398.html) require a specific mousepad with a calibrated grid printed on them. The mouse can only report its movement relative to this grid (rather than relative to an arbitrary surface as with modern mice). -- Paul Saunders
