Many kinds of hardware are getting smarter.  I was a bit startled when I
took my new shaver apart and discovered that it has an IC of some kind
inside it!  Probably some kind of power-control chip running switching
hardware -- the thing can be charged from 110 or 220 without any flipping
of switches, and it knows when its battery is getting low.
