Would you replace your numeric pad with a trackpad?
cmos: Possibly.  I would probably prefer it in the same place as on my laptop, below the space bar.At this point why can't we put the trackpad on top of all the keys?  The action of pressing keys would not change, and 'stroking' them would move the mouse.  The most brilliant design change for the ipod was when they put the buttons underneath the trackpad.It would either be really annoying or super cool.
