This is completely wrong. USB is a hog, IEEE 1394 joysticks? Almost
every sound card out there...modern...have game ports that are useful
now. USB is an evolving and often broken standard. Your idea of obsolete
is not completely wrong, but it is far too wrong to go about it this
way. And printers or serial mice?
