Correct.  If you are doing the same thing you were doing when you bought the
system, there is never any reason to upgrade it.  It doesn't get any slower over

A week is long enough to go out of business.

I'd have to duplicate all the hardware, too: scanners, tape drives, CD burners,
modems, printers, and so on.  Too expensive, and no space.

Additionally, some software on the machine requires a dongle, so there is no way
to run it in parallel on two different machines.

If you have complete duplicates, it is doable, but that is expensive.

Your UPS didn't protect you?

How did you manage to take delivery on a new machine in one hour?
