Sensors in PCs - Why not?

Why do we need an external sensor to recognize wireless keyboard & mice? Jzz make the sensor & driver configurable as part of any PC. Something that is in-built.

Like the remote control frequencies that can be configured with ease in the new Honda Odysseys. That sure is customer friendly. Almost every1 out here in US has remotes inside their car - open garages, open apt complex gates.

Like the cable remotes - Configure to play any DVD player. Makes things really ez.
