Yes, I have used that resolution with Fractint, but the computer was
booted up
in Windows (95? 98?).

How often a day do you do that on your desktop computer? :P

Not often with the keyboard, but I often swap my USB mouse between
my desktop computer and my work laptop. An old PS/2 mouse couldn't be
used like that (and not only because the laptop as no PS/2 port).

The actual benefits are more in that...:
(1) You don't have gazillions of different connectors.
Imagine that in addition to FireWire and eSATA for external bulk memory devices,
network connector for network (of course), DVI and HDMI for display, and
what-have-you-not, you still needed the good old PS/2 for the keyboard, another
(don't mix them up!) for the mouse, parallel port for the printer and EEPROM
flasher and dongles and what-have-you-not, the Gameport for joysticks and MIDI,
and last not least RS232 for the modem and diverse like chip-card readers and
stuff alike.
PS/2 is just two connectors to get rid of, but what sense would it make to
introduce a "universal" peripherals interface to replace a host of other
connectors, but stick with the old ones for keyboard and mouse?
(2) You can have multiple keyboards at once, and/or keyboars with non-standard
keys.
Like, for instance, those nifty multimedia keys. Or one of these beasts, for
that matter:
http://catalog.belkin.com/IWCatProductPage.process?Product_Id=393741
(Yes, they did similar with PS/2, most notably for joysticks with gazillions of
buttons and switches; but would two of such products from different vendors be
compatible with one another?)
(3) The keyboard can double-feature as a hub to connect other periphery to, like
USB sticks for instance.

Hum... I guess other people would buy another mouse, right? :P

This was the rescue disk, which was basically an MS-DOS disk. You got a
command prompt so you could run chkdsk and fdisk. No extra drivers.
Now, it's possible the BIOS is taking the USB and putting it out to the
appropriate BIOS calls. I suspect that's what "legacy USB emulation" means
in the BIOS settings.

There were no graphics or mouse or anything involved. Since the topic was
the complexity of graphics programming, I just checked to see if the command
line came up and ran.

Yes. PS/2 is the little DIN plug. Anyone still have one of the full-size
DIN plugs they used before that?
> In any case, aren't there adapters to convert USB to PS/2?
Sort of. It's more like some keyboards are built to recognise that plug
being on there and switch to sending PS/2 signals. You can't take every USB
keyboard and use it with the adaptor.
> Never knew what the benefit of a USB keyboard was...
You can have more than one, you can put it on a hub, you can hot plug it
between machines, and you need less driver software to use it from scratch
assuming someone already gave you a USB driver.
For the average desktop user? Not a whole lot.

Mostly useless, though. If you connect eg. a USB mouse to a Win98 system,
chances are that it won't work. (You have to install some driver.)

My keyboard is so old that it has one of the big plugs. I have to use an
adaptor to connect it to a modern PS/2 connector.

Yeah, I have one of those left too, but I don't use it any more.
I recently spilled on my usual keyboard, so I switched to another I had
sitting around. I hadn't realized how much I touchtype even things like
"home" and "end" and "page down". For several days I was hitting "insert"
instead of "home" because the block of keys is across instead of down on
this one.
