AmigaOS is the Elvis of operating systems, it had the good sense to die about the time it started going to seed, so we can all morn what might have been unencumbered with the vision of an overweight 70 year old trying to swing those hips.
I think Eric Schwartz' latest video captures that, the Amiga as a once famous singer now singing karaoke and pretending that she really still matters. AmigaOS would not have aged well, it would have put on weight like all the other operating systems. It would have to support all those things that we expect a modern operating system to support. It would have to have gone intel. Tripos swapped out for a unix variant, etc, etc Everything the Mac haters moan about would have happened to the Amiga.
