I am afraid of rebooting an old box at $WORK that has had 2000+ days of
uptime - simply the hardware may have died somewhat and it may not start
up after a power-off.
Transporting a machine with UPS to save uptime seems like a fun project,
but not necessary good for the final result (HDD-s and vibration etc).
But uptime itself really does not matter for me - predictability and
I want to see my new configuration actually work after a reboot or power
failure, or the changes are not complete and bite back later in
I want at least known vulnerabilities fixed - software becomes more and
more complex and security is harder and harder, so postponing patching
is mostly lying to myself.
If availability matters, I want use a cluster anyway (and if it really
matters, it has to be geographically distributed). But if I have a
cluster then reboot time does not matter much - even my old IBM RS/6000
spending half an hour for POST would do ;)

Nope, running Windows seriously stopped with Windows for Workgroups :)
