When it was time to go 16 bit my brother had just started working full time so he bought the Atari ST when it dropped in price. The Amiga 500 was still more expensive so nobody around us had one. Same reason everyone in my home town had speccy instead of C64, and we all used tapes instead of floppies! :)

Now I have a bunch of Amigas but I also have a couple of STs because they are still my first 16 bit love ;)

I got a 286 PC in 1992 I think, same time the A600 was announced. It was 12mhz and I chose the 40mb hard disk instead of a colour monitor because I wanted it for programming rather than games. That of course changed as the VGA+Sound Blaster PC become the dominant gaming platform :)
