yeah, the hockey puck mouse was just pitiful. The head-scratcher for me with the new mouse is the gesture of 2-finger swiping (laterally) while your other three fingers are (presumably) stationary on the mouse.  It makes my hand ache just thinking about it.<p>loved the fully articulating arm on the old iMac--one of the sacrifices they've made in their quest for aesthetic minimalism (which I appreciate, mind you, it just sucks that you can't move the display easily anymore).
