Got new mini at frys on 23rd. Base i5 2.3 and upgraded to 8gb ram. Running Lion and downloaded SteerMouse as suggested here. Works great. Got this mouse. http://www.officemax.com/technology...ne~1^region~1^param~return_skus^return_skus~Y Except mine is darker purple but same model number. And was 10 dollars. Instant 5 dollars off. The side buttons go back and forward in safari. But steer mouse lets me assign those as button 4 and button 5. But if I say open a program and select dashboard it now opens dashboard so great. Just what I needed. But clicking the button again does not exit dashboard. Only F12 does defeating the purpose of the mouse.
