But considering that two NICs cost less than that cable, I'd need a
pressing reason to purchase the cable instead.
There is a perceived elegance aspect.
There is also a practical aspect the only known working and
conveniently physically accessible ports are USB.
USB-Ethernet dongles would be a lot more useful in the long term than
USB-Serial dongles. RS-232 had a really good 40 year run, but for
general communications it was mostly obsolete nearly 20 years ago. You
mentioned file transfers--I can't think of any applications where
that's going to be better over a pair of USB-Serial dongles than a pair
of USB-Ethernet dongles.
