The ATARI ST was a nice computer. Some people covered some of the things I wanted to say. I would like to point out the following:
-90% of the Amiga games up to late 91 were pure ST conversions. Only thing that changed a bit was the sound.
-GEM was not the best OS, but you could see it running. To use WB back then, you had to insert the floppy disk, wait some time and then insert another disk just to format it. I preferred to use X-Copy for that. On the ST, GEM was providing basic things instantly. The OS was in ROM and you could do virtually anything in seconds. We are always talking about A500s and 520STFMs here.
-ST from STFM onwards had a TV modulator. Amiga was charging extra for that.
-Atari's B/W monitor was just lovely. It is one of the main reasons why the ST became popular to sound studios, DTP etc. The ST had by far more solid pro software than the Amiga. Amiga users started realising that their computers can be used for more things than play games and using X-COPY with the arrival of A1200 and the cheap HD IDE technology used.
-The STE was a computer that very few people explored. Believe me though, I have seen things in STEs that made my jaws drop. All these after I bought a A1200 and a A4000.
-Community-wise, the ST users were mad. They used to have the Demo wars that was only good. Why? Because it was these demo wars that allowed users to meet and create companies that made brilliant software like Thalion. Thalion was nothing else but old ST demo coders. If you want to see ST games with 512 colours used at the same time, go for Thalion games. One of the best computer musicians ever, Jochen Hippel was member of the Lost Boys and Thalion.
-Overall, I never got into the hype of Amiga users slugging ST users off. All I could hear from Amiga users back then was "Your computer sucks"... All this based on games!
-Atari, as a company, lasted longer than commodore. It was commodore that died first and then Atari.
-I still laugh at the post saying that the Falcon was produced as a dev machine for Falcon! Jesus, I needed a good laught today....
