Doom was the death knell for my Amiga days as well. That and by that time, IIRC, it was obvious that Commodore was going under fast. I don't want to go pull out an Amiga and play, but it's rare to experience something that actually feels like a whole new ball game. (The Oculus Rift is close.)
After my first machine, an Atari 800, I had an Amiga 500 and loved it. But I didn't keep up with industry news at the time, so my first indication that All Was Not Well was when I walked into my local Amiga store (Omnitek, in Tewksbury, MA) and the Amiga stuff had been moved aside to make room for IBM PC-contemptibles... some of them with Commodore badges.
