You can famously run Linux on anything. And, when I say anything, I mean anything, e.g. a Nintendo Wii, an iPod, DeLaval’s robotic system for milking cows, and possibly even a dead badger. Only Doom may have been ported to more devices. But, for practical purposes, all good things must come to an end, so Linus Torvalds is giving serious thought to discontinuing support for the 486 architecture.
