There are a lot of good responses. It is important to note that back when Doom was written, the hardware was pretty weak compared to today. Just like the remarks about landing on the moon with less computing power than a modern calculator, Doom requires little power compared to what we have today.

Additionally, during this period of computing history, developers coded their games and applications with significantly less overhead than we have today. Developers still need to code today, but much of the code is written using development platforms to make it easier and more powerful. This requires greater overhead than if you wrote all your own code from scratch.

So you have a game, with a familiar playstyle (as one of the first FPS games), optimized, and old. That means that it can run on things that have no business running a FPS game. (Even if it is just using the device for a display).
