In fact using a wireless keyboard you're just increasing the chances of 
someone get your signal:

- through the air (exploiting some fail on the encryption)

   *and*

- through the eletromagnetic field generated by the keyboard (the same 
way with wired keyboards, just with a signal slightly weaker for the 
absence of the wire).

Perhaps as Cédric have pointed, someone that could get as near as to get 
the signal (and carry the equipment to do do this) probably would use an 
easier way to spy on you.
