Apple placed a patent for this a while ago, I believe.am i alone in thinking the issues could be addressed simply by placing a full touch screen on the front as speculated and a tactile click wheel in the back. in the nano form factor i think that it could work - however what would the added cost of production be? too high? and potentially make the nano thicker which could be a negative given the focus on the size in the nano line.... thought? am i just crazy?
