Finding laptops with a serial port has always been difficult, much less
finding a laptop with two serial ports if that's what you need. Multiple
serial ports have always been a problem with desktops, too, if you need more
than the two that come with the machine. (I'm speaking of situations where
people used to need multiple serial-based products on their machines in
commercial and industrial applications, not hobbyist setups or VAR systems.)
Now, there is USB. Virtually all computers have it, and have had for at
least a few years now. Need to hook up more stuff? No problem, get a hub.
You can even pull power from the USB port, not much, but its there and a lot
of times you can use it.
Hey, I miss serial communications too. It was easy to deal with, even in
asm. USB definitely ads a level of complexity. But times have changed, and
USB is superior to serial for many different types applications.

Overkill, by who's definition?
