I owned just about every Amiga model put out in the US, but the A2000 was the workhorse business machine. Coupled with the video toaster card and lightwave it was a video production tool that cost about 1/10th to 1/100th of what it would cost to assemble all of the discreet machines it replaced. With the addition of the Flyer card it also became a non-linear editor, a tough feat in those days. I did a lot of good work with my A2000. I had the SCSI controller and a hard drive (probably 40 - 80 MB in those days)
I was also big into Amiga gaming as it was way ahead of its time compared to PCs and Macs. You would pop in something like Shadow of the Beast and just marvel at the arcade quality parallax scrolling and really nice stereo sampled sound using all those nice custom chips that PCs and Macs did not have.
The linked article is very short on details (there are many) for those of us who lived through it, but even after all this time my own memory of specifics of things is basically gone.
A good book to know why all of this did not last or evolve is "The Rise and Fall of Commodore". For those of us who started with the C=64 era and went out till the end with the Amiga, it's an enlightening and sometimes frustrating read about the politics behind our favorite company.
I think that outside of serious collectors and computer history museums, trying to maintain and fiddle with the hardware today is, well, a dedicated hobby. Best of luck. You're often better off with the emulators out there to get your feet wet.
Within the limitations of technology at the time, the Amiga era was a grand ole time, and we all knew we had the best at the time. Thanks to marketing by other companies who think they invented everything, it will indeed likely be relegated to a forgotten footnote of personal computing history. For those of us who lived it, it was a way of life.
