I was always of the opinion that the thing that made a desktop PC different from every other gadget I owned was that it wasn't a single thing but rather a
soft device.
One minute it's a wordprocessor, the next it's a calculator. Later on it might be a television or movie viewer, or a weather station, or a research organizer, or a recording studio or musical instrument, or a planetarium, or an electronic circuit simulator, or a design and drafting tool - with soon-to-be affordable 3D printing capabilities for one-off manufacturing or prototyping...
Time was when each of these things would require a separate hardware device. Now they can all be done on one infinitely reconfigurable
soft machine.
I don't know anything else that's quite like that. A PC itself is
nothing really. Just an inert hunk of patiently waiting electronics - until you load a
program - at which point it can literally become
anything. It's like the genie in the bottle saying:
What is your command Oh Most Nobly Born Prince of Princes?Yeah...
You ain't never had a friend like ME!Never ceases to amaze me that something like that actually exists.
