I used to work in video production and I never spoke to a person that currently used Amiga anywhere. I realize this is totally anecdotal, but the Amiga hardware must be pretty tightly integrated into your workflow if you're still using 20+ year old hardware that's a tiny fraction of the speed of more flexible and standardized desktops now, with software that you can easily and cheaply hire someone out of college to operate since they probably have already trained on it.

Perhaps a few TV news outlets are still using it since the turnaround there is so tight that everything needs to be "just so" to meet your deadlines, but even then, I have difficulty believing with the move to digital and HD that you could even get your footage onto an Amiga and work with it. I can't believe the hardware could handle HD.
