We have touch tech, why not implement that in home macs, instead of using a mouse why not touch the screen like on the iPhone. Multi touch could be used, use a keyboard could still be used, but use mutli gestures to move and zoom in on the comp using touch. Touch screen have been around for a long time, why not use them in ordinary macs. The only reason for a mouse these days is for graphics or design, but not all of us are designers or graphic experts, leave room for a mouse, but bring this brilliant touch tech to the home macs. I'm not to sure if this has been mentioned but i think it is the next best logical step.
