I suppose it depends what hardware you're working with. Most of the
systems that I use to dump data are old 486 or Pentium PCs. Even 386 and
286 machines are useful. And these are machines that will be around in
droves for years to come. I can also stick an ethernet card in them with
TCP/IP drivers and attach to my Windows XP server. My older PCs don't
have USB, and even if I could plug in a USB PCI adapater (most of them
also don't have PCI slots) I wouldn't have the drivers.
At any rate, I don't think the point was pitting USB against serial but
had more to do with not focusing on what tie you should wear when you're
going to dig a hole.

Well, for our purposes, it's far more "universal" than USB.

Guess what? Serial includes even more systems and a serial connector can
be wired up for any connection without much trouble, usually with just two

Have fun programming the drivers for that.
At any rate, as long as we have USB to serial converters then that at
least guarantees that people investing in contemporary hardware will still
be able to connect to their vintage computers.
And one other point that Dwight made that can't be ignored is that USB
does require specific drivers for the device on the other end, as opposed
to serial which is a just a simple, dumb data connection. Why does
everything have to be "smart" anyway?
I'll continue to prefer straight serial for some time to come.
