Amiga was definitely in a class of its own!
Incredible gfx for the time (like 4096 colors in early 80's when PCs had 4 colors), stunning dedicated chipset for audio (4 different outputs), and so on.
The fact that it was so good for games made people believe it was only a good games console.
Powerful applications came out, and in fact many of those that are "industry standard apps" were born on the Amiga (Lightwave, Cinema4D to name just two).
The OS was super stable and had very efficient multitasking. Screen dragging was another cool feature. You could just have one app open on a screen, and drag the whole app around to reveal another screen underneath.
In Europe it became the de facto standard for gaming (like PS now), SimCity was born on Amiga. But people never thought it was a computer too, and very few used it to do anything serious. They just got a PC for that.
At some point all my friends just moved to PCs to do serious stuff. I stayed with Amiga. Well, we had a project to do at university... I used a freeware spreadsheet on my little Amiga and got top marks, they didn't even thought about using Excel and did all calculations by hand. If they just used their amigas more...
Amigans always thought different, and many Mac freaks come from Amiga. We shared the same CPU, same philosophy, regardless of ideology....
