Sony has released a new "PowerPoint presentation" 2.4GHZ wireless mouse that features 4-buttons and 800DPI resolution. What is truly unique about this mouse is the joystick pointer where normally a scroll wheel would be located. The joystick is used not only for scrolling vertically and horizontally, but when it is used as a presentation remote, the joystick can move the cursor on the projector.Now if they added a laser pointer this truly would be a killer gadget!]]>
