That doesn't surprise me, because I already have a Chromecast.

And there are many other instances of small cheap computers too, but my point is this: once you've seen a little device that plugs into a TV/monitor and does stuff, you've already seen a computer, because all these things are computers nowadays. Hardware has to be seriously small and special-purpose nowadays to even consider a microcontroller. It's the age of system-on-a-chip.
