Logitech dosen't seem to sell any wireless keyboards seperately. I believe the same keyboard comes with the LX 700 set. What's nice about the MX 3100 set is that you get the MX 1000 laser mouse with a matching keyboard and a base station that will work with the MX 1000 (it needs a charger capable of recharging Li-Ion batteries). What I really wanted logitech to do was to release the Fast RF version of the DiNovo keyboard and media pad set with a silver matching MX 1000 and a base station to handle all three devices.
