 Exactly.  We're a long way from the time that "embedded" meant 68HC11
 or 8051-style applications.   I know that there's at least one vendor
 that sticks a Linux system inside what amounts to a 100BaseT female
 connector.  Is it embedded?  I'd say so.
 The absence or presence of file systems is neither here nor there.  I
 wouldn't dispute that a $20 MP3 player, for example, is an embedded
 application, but there's a file system in there for certain. 
 
   Yeah, I really can't disagree with that.  That's only how I tend to
think of things.  One really has to consider them on a case-by-case
basis.  There's at least one popular MP3 player that will give you a
UNIX shell prompt if you frob it just right. (iPod Touch)
   Kinda like the "what constitutes a minicomputer" debate.  Nobody
disagrees that, say, PDP-11s are minis, but nobody can coherently tell
you why.  People who know about this stuff just "know".
  Operating system?  Well, there are OSes that fit
inside a low-end
 PIC.  For that matter, there's a version of Linux that runs on a
 PIC32 ?C. 
   Indeed, 2.11BSD has been ported to PIC32!
  Rabbit-hole indeed.  The boundaries are very
indistinct.
 Particularly when someone is talking about internet-connected home
 refrigerators. 
   Agreed 100%.
  Technology has a tendency to obsolete terms of art.
On my local
 Craigslist, there's a seller who advertises a "minicomputer" for
 sale.  It's basically an mobile device with an external keyboard. 
   Yes, that drives me nuts, though I suppose it's unavoidable.  Is it
Maxim or DalSemi who sells ICs in a package called "Flip Chip"?
   And no matter what terms of art become obsolete, we are doomed to
argue about them here. ;)
