So are you telling us that you've NEVER had to haul a monitor across
the office to plug it into a server to see what's gone wrong?
There are occasions when you *absolutely* need a monitor, and there's
just no way you can manage without one. Ok, so Windows doesn't count,
and GRUB may operate with a serial-console, but it doesn't need
saying here that there'll be times when you need to enter the BIOS.
Can you change boot options on a LiveCD with a serial-console?
Possibly so, but for every situation we can cover and resolve here
discussing this in an academic debate, there's a SNAFU waiting to
ensnare us in the real world.
I guess I'm just saying that something like is just another tool in
the toolbox, and if you were to try the DRAC4 hardware-VNC unit
installed in the Dell server I've been working on the last couple of
days, I'm certain you'd agree what a handy tool it is to have.
IIRC this option cost the site £110 or so when we bought the machine
2 years ago. When the system finishes shutting down, the "screen" -
in a window on my laptop - goes blank for only a second and it is
*such* a pleasure when the BIOS logo so quickly comes up. You know
that everything's working fine so far, and that even if the o/s
doesn't load, you're covered - you've got the tools to deal with it.
I'm sure we've all had occasions when we've rebooted the server and
it *hasn't* come up, and we've all had occasions when we've issued
the reboot command and sat there crossing out fingers for several
minutes. I can tell you that this hardware-VNC unit in this machine
is like God's gift of reassurance - especially when you're working on
an important server from across town.
Oh, and besides - lots of people DO have to work on Windows, and a
serial console is naff all good to those unfortunates.

These still need a monitor. I kinda like the idea of these - they've
been around for a while - for ad-hoc dual-head uses, for hanging a
monitor off a plastic ADSL router or just for silly-large multi-head
japes. But convenience aside they solve few problems that would be
beyond the capabilities of a handful of old PCI graphics cards.
