Since there have been a lot of threads along the lines of "what games do you play?", "what kind of utilities do you use", etc. I was curious, does your Amiga actually generate some profit or significant income for you? Did you earn more than what you invested in the equipment?
I'd say yes.
Although not in the direct sense you mean - but back in 1988/89, when I got my first A500, this machine taught me the "modern" way of computing (from 1986 on I had an CBM 610/620 and learned coding in CBM Basic 4.0 like hell on that "beast" and created a sort of GUI for it - somehow similar to DOpus).
It helped me a great lot during my CAD analyst postgraduate studies and I was "computing" on it day and night. My wife back then asked me at one point:
"You are sitting at your computer day and night - but I can't see anything coming out from that. What is it good for?"
Well, when I got my current job as an system admin back in 1998 and a quite good payment, I reminded her of her question from years ago, showed her my latest salary printout and asked her:
"Can you see the outcome of it now?"
Leaving aside obvious people like Jens :-) are you someone who programs software, or produces videos or artwork, and have been successful at it?
No.
Has there been anything that you have done on the equipment, gotten you some recognition beyond our little community?
Done a lot of CAD/CAM/CNC on my little A500 and learned other things like DBase, MS-DOS and even Wiondows as well on it. Got a good degree from that and based on I have a good and well payed job today, if that counts.
I remember, quite a few years back, some guy had a scheme for putting Amigas running Scala (or some such program) in mall kiosks and generating income from the advertising.
As I said - for me the benefit was more indirect...
EDIT:
Oh yes, and I certainly earned a lot of more money with my job than I ever will be able to spend for all my Miggies...
