Aren't they useless? I have only used them three times since 2001.
(1) Boot-up disk creation
(2) Drivers disk
(3) Transferring a file from an ancient PC

USB drives? Meh. They're not really a "standard" and are hella expensive compared to a CD-RW disc.

You really have no concept of upgrade cycles on computers running industrial-control applications, do you? (But then, most of the high-tech industry doesn't, I reckon) I've come across SCADA applications still running on 386 processors and I'm sure there's older stuff out there yet. If there's no payback to an upgrade on a system like that, it isn't done, period.
The first factory (pulp mill) I worked at had its entire woodroom control package (the interface to the PLCs, that is) running on two 386 PCs (w/o ethernet, as the communication to the PLC was via RS-232, another technology that new computer makers are loathe to support) and the software was already obsolete and the company who made it out of business when I got there (in 1996). It still ran 5 more years before one of the PCs finally died and they had no choice but to upgrade it and invest in a new control package. That was a substantial investment and it didn't make the woodroom run any better (thus no payback), because the underlying PLC system didn't change, it was only the operator interface that had to change.
Scenarios like that are not uncommon in industrial control applications. Floppy drives and serial ports are a must in our line of work.
(EDIT: they might even have been 286's. They'd been in use for about 3-4 years before I got there, what year did 386's hit the market?)
