That something has a CPU doesn't tell you whether it is a general
purpose computer.  What tells you if a device is a general purpose is
whether it is intended for particular uses or not (the key word there
being "purpose").  More importantly, if you view every Thing as a
general purpose computer you are missing an opportunity to impose an
engineering constraint on the problem space.  If that in turn let's you
easily solve for the general case, you've had a huge win.
