+2 Oscar for giving me this name.

A more apposite (to computers) experience:

Ive a computer whose OS I wanted to upgrade without disturbing the
existing setup. Decided to fit a new hard disk with a new OS.
Installed the OS on a new hard disk, fitted the new hard disk into the
old computer and rebooted.

The messages that started coming were: New Hardware detected: monitor,
mouse, network card etc etc. but not new disk!

Strange! The only one thing new is not seen as new but all the old
things are seen as new.


So…
Ask a layman whats a computer and he'll point to the box and call it
'CPU'.
Ask a more computer literate person and he'll point to the chip inside
the box and say 'CPU'
Ask the computer itself and it says 'Disk'.

Moral:
Object identity is at best hard -- usually unsolvable
