................ All the so called Amigans here are now Windows, MacOS, iPhone, Android, you name it fans, but not Amiga enthusiasts. At least one can hope they will not ruin the English Amiga Board.
am I the ONLY one that actually
learned something from using an Amiga (my First Computer) and that this knowledge translated into how I use Every single other device I have ever used since?

I honestly don't understand this attitude. (meaning that a person is not a true Amiga user unless his finger are actively on an Amiga)
Frim my Amiga I learned how to be frugal using my programs (started out with bare bones A2000, booting from floppy with the smallest amount of memory you could get at the time. ) I still learned how to use DPaint with that set up.
A few years later when I moved to LA and was looking for work at an animation house they "tested" me on their proprietary paint program.
It was a sad little affair where you had to exit out of Every tool to Enter another tool. and you could only use ONE tool at a time. recall DPaint let you use several tools at once. I picked this up in literally seconds because it was WAAAAAY easier to figure out than DPaint.
The person testing me was absolutely astounded at my prowess - I kid you not.
I wasn't trying to show off. Amiga just taught me very important techniques in figuring out how software worked and because it was WAY ahead of it's time made ME ahead of my time.
This gave me an edge that others did not have.
laugh all you wish, but I am an Amiga Snob for a really good reason. I carry Amiga with me in my brain even if I have not touched my old Amiga 2000 is a long time. It exists where it counts. And continues to inform my work no matter what device I use.
