Far from all systems have Bluetooth hardware. Particularly, it is
uncommon on desktop systems. While laptops are common in many
settings, pure desktop systems still serve a large, legitimate niche
even in new installations.

The idea with using wired USB was to force the user to make an
informed decision to have the device interact with _the intended
system_, and not some other one that merely happened to be in radio
receiver range at the time.
