My Amiga 2000 was my very first computer. It taught me everything about how to use a computer. Because it was logical I was able to see the relationship between icons and CLI commands. I was able to play around and figure things out.....I know it would never have been so easy or fun on another OS.
My Amiga let me see the possibilities of a computer as an artists tool. It was THE most important purchase of my career. I learned how to multitask - I still don't think you can do that on a windows machine. it DOES feel different.
Amiga let me see how to solve problems - this is a subtle point and I don't think I can fully explain it. I was able to see that computer related problems can be solved in a variety of ways. You just have to keep looking and you will eventually find it.
These and many other lessons were used during my career, even when we had to change to other computers.
"Amiga" is not just a computer, it's a way of thinking and creating. Which is why it will never die.
