And why is
this a Good Thing? My point is that it's to be exptected that
a modern PC will have a keyboard and mouse connected to it. Why does it
make any difference to the used if those can be connected to 2 of the USB
ports or to 2 specific connectors for them?
You've already asked that.
NOW imagine that a whole bunch of unforeseen devices - printers,
cameras, touch sensitive tablets, disks, modems, e-book readers, 'pen'
drives, portable audio players, ... - arrives. Are they meant to use
PS/2? Are they supposed to have individual connectors? USB is no more a
silly idea than RS-232 is.
That is NOT WHAT I AM ASKING ABOUT. I sam specifically considering only
keyboards and mice. I happen to think that USB is a useful interface in
some situations, for example for external memory devices. That doens't
mean I have to think it's the best interface for all applications no
matter what marketroids may claim.
FWIW, I don;' consdier RS232 to be a universal interface either. It's
one I use somethmes when I feel it's the appropriate choice.
