For many embedded apps cost and or board space is very much a concern
and to add the $5 for the superI/O just to get a serial console is out
of the question.
Intel has been trying to push the serial ports into legacy for the past
few years, so serial ports have been disappearing from many boxes. A USB
console may be the simplest approach to development and debug on the up
coming machines.
