I stopped using my Amiga around '95 when I started working on Silicon Graphics computers with Alias Wavefront Power Animator. At about 1999-2000 I bought my first PC. Mainly because of the internet, but also because the 3D cards had caught up with the SGIs and Maya 3D finally arrived for the PC.
I still have my Amiga 1200 though, and I use it from time to time to play the old games.
