What was your Amiga moment?

2 Amiga moments for me
First was playing Lotus, Buggy Boy and Xenon 2 on my cousin's Amiga 500 back in the heydays and being totally blown away by it (while we had a 386 with VGA at home)
All games were in 'vga' (as I considered it) with awesome sound while I most often had CGA or EGA games with pc beeper, and if I were in luck, VGA support.

Later on, in 1999 I had a powerful Pentium 2 with 3dfx pc, a friend of mine offered to buy me his Amiga 500 for a small price, and I could use a spare computer for entertainment when my big pc was doing heavy work (windows 98 wasn't that much multitasking). So I replaced my old 286 monochrome as 'co-pc' with the Amiga.
First I thought it was broken, as I dutifully inserted the workbench disk and then inserted the game disk, and almost all games were displayed as 'NDOS'. But then one lucky day I forgot to eject the disk, and the next time I powered up the Amiga, I was being welcomed by the awesome intro of Pinball Fantasies
That was the second time I was blown away by the Amiga, years after it's heydays

Windows 2000 was the best.  It was the first with the NT4 kernel with the 9x interface.  XP moved some portions of the outer OS into the kernel and forced the IE integration as well as a bunch of other crap that wasn't needed
2000 was way more stable, faster, more secure.

Most people forget 2000 because XP came out so fast due to the IE court case.

Windows NT4 had a 9x interface. Pre-4 NT windows versions had a Win3.1 interface.
Windows XP was practically based on Windows 2000, but the main 'difference' was that they ported the whole up-to-date directX library to it. Perhaps also some other backwards compatible features came with it and some server-specific functions were left out in the home version, but I don't know the details of that.
Perhaps those backward compatibility features rendered it somewhat unreliable but the main reason I think is badly written (often pre-installed) virusscanners/firewalls that clogged the system most often over time.
