This is a brief review on the Toshiba mini retractable laser mouse (part number PA3569E-1ETA). There's not really much information out there about this mouse. I picked it up through Amazon for just over £10 with free delivery. For use with Ubuntu GNU/Linux, I wanted something that would work out of the box without requiring pointless drivers. It also needed the middle button to work (most mice are sold as only two-button).
