For purposes of connecting old storage to new computers, Barry's
point stands. The discussion here doesn't really include development
hardware, low-level controllers or embedded systems. If I were going to
design hardware for a "next-gen compaticard", it would not be on a
I won't argue that serial is underrated, and it's true that it's not
disappearing, but a rising percentage of commodity desktop systems come
with no serial interface.
It's the usual story that numbers, not quality, define success. USB
is going to be "it" for a good long while.

Just to throw a monkey wrench into the mix, we might consider
ethernet. Even more universal than USB, doesn't exclude older systems,
and only comes in three common connectors (that I can think of. A lot
of the appliance-oriented microcontrollers and CPUs now have builtin
ethernet, right? With microcoded TCP stacks and even DHCP clients.
Plug your 8" floppy drives into your *network*....
I think that while the hardware costs would be higher, the
development issues would be greatly reduced.
