It's a tool, not a work of art.
You just said it all.
This is why hardcore computer people generally do not understand the
importance of polish and shine. Most of you are quite happy in a world
of grey (beige?) computers, looking at a grey screen, sitting at a
grey desk, eating a grey sandwich in a grey room. Great, very
productive. Most of the public thinks otherwise.
It's perhaps cheaper now that so many printer
manufacturers have gone down
that route. But the level of complexity of a point-to-point parallel system
must be a lot simpler than a serial bus, surely?
Once the initial engineering gets done, it is all about production
costs, and this is where USB shines.
