It's actually almost 30 years to the day since the launch of Commodore Amiga.
One of my best memories was Christmas 1985, waking up to my dad fiddling with the A1000 in the living room. He learned enough from the ComputerLand salesman to type `dpaint` at the `AmigaDOS>` prompt and launch the coolest thing[2] I'd ever seen.
That computer was my only machine from 1985 through 1997, when I finally got a secondhand 486DX2-66 to replace it. It wasn't until well into the 2000s that I had a computer that could do the things I could do with that Amiga.

"So finally Amiga-like long file names and plug and play like with Amiga Zorro bus. But why it doesn't still let me to rename volumes as something else than single drive letters C, D, E... etc.?"
My 1995 self would have been so disappointed to hear Windows is still stuck to drive letters in 2015.
So mounting a filesystem to a directory is not same. When directories are mounted, you need to provide volume first and then you can refer to it. You could name some USB stick as "Important Files": and whenever you copy or save anything to drive "Important Files": the system would ask you to provide this named volume.
I do remember AmigaOS tweakability, it's still unmatched by anything modern.
