The Amiga was really ahead of its times. It came out in 1995 (just a year after the first Mac) and it already had preemptive multitasking, custom audio and video coprocessors (with 16m colors, stereo sound) etc.
I still have my Amiga 1200 (although my first one was an A500).
I still have two A500+ machines, one of which has a 42MB external HD with this program on it. :)
I did a 192-frame, full-color animation in DPIV back around 1996. Took me five days to finish. Still trying to figure out how to migrate it to my XP box.
Oops, I still have my A1000 in the garage, KS1.1 disks and all.
When I was having a book clear out recently, the Hardware Reference Manual, ROM Kernel Manual: Exec, and the printout of Markus Wandel's Exec disassembly (1) all went onto the 'classics' shelf.
I'm struck by how incredibly simple the software looks. It's admittedly a very unfair comparison, but when I compare the UI and ease of use in that demo to something like Blender, it does make me wonder if graphics software has fallen off in usability over the years as more and more "stuff" gets shoved into it.
