I remember drooling over the 486 back in the day. Playing Descent, Duke Nukem, Raise of the Tirad, Doom and rocking Future Crew demos on a 486DX2/66 was the bomb.
Of course the 486 has little value today, thats not because it was crap hardware, it's because the platform didn't die. Newer and better products followed, unlike Amiga. This is why a 486 can be had for free but a tricked out Amiga costs more than a Mac Pro.
