If IBM made toasters...
They would want one big toaster where people bring bread to be
submitted for overnight toasting. IBM would claim a worldwide market
for five, maybe six toasters.
If Xerox made toasters...
You could toast one-sided or double-sided. Successive slices would get
lighter and lighter. The toaster would jam your bread for you.
If Radio Shack made toasters...
The staff would sell you a toaster, but not know anything about it. Or
you could buy all the parts to build your own toaster.
If Oracle made toasters...
They'd claim their toaster was compatible with all brands and styles of
bread, but when you got it home you'd discover the Bagel Engine was
still in development, the Croissant Extension was three years away, and
that indeed the whole appliance was just blowing smoke.
If Sun made toasters...
The toast would burn often, but you could get a really good cuppa Java.
