Having heard Elecia White (@logicalelegance) http://embedded.fm/ ask
every guest what an embedded system is, I'm leaning toward what Sean
said, but I'd phrase it in reverse.

A general purpose computing system is what an embedded computing
system isn't.

Where an embedded computing system can be easily repurposed or
reprogrammed by the ordinary user, it leans toward not being
"embedded".

So generality is an attribute of a general purpose system, and
non-generality is an attribute of an embedded system.
