*cough* Acetronic 2000/Radofin/Interton VC-400 *cough*. Will this appear in the voting list or am I just too retro for you all? 
This machine had my favorite controller of all time. The emulator for it is just about the last regularly updated Amiga application around, but it is also pointless as you have to have the original controllers to appreciate the machine. You move the yoke and it is like you are connected directly to the screen. I love the directness and low brain power required for most of the games. And the games are completely different to what you find on other machine. Some odd little ideas which we never explored further in other machines.
