It is, and is sold as, "a system on a chip" near enough. If I buy a Pi, *I* have to provide the SSD. *I* have to program the SSD. etc etc.
In other words, as supplied, the Pi is as functional as a normal desktop without a hard disk.
I can then turn it into an embedded system (for which purpose it is eminently suitable), but it isn't that in and of itself.
