I saw an Amiga 2500UX once. It was a demo unit owned by Creative Equipment in Miami, but from what I remember, there really wasn't much you could actually *do* with it at the time unless you were a college professor or grad student with a Unix-related obsession. There wasn't really any commercial software for it, and I doubt whether it even shipped with the necessary libraries to build anything more ambitious than maybe "Adventure", "Spacewar", and "Life" -- all of which were undoubtedly cool in the 70s, but didn't seem very interesting compared to "Bard's Tale", "Federation of Free Traders", and "Lemmings" ;-)
Like I said, Commodore killed the development of Amiga Unix, which I think was a bonehead move on their part. Amiga Unix would been a favourite for those schools teaching CS, and the student wouldve brought Amiga Unix into the workplace once they moved on.
This is not the first time Commodore gave up a golden opportunity to get into the schools. It made the exact same bonehead mistake with the Commodore PET and Commodore 64. It handed over that market to Apple, where the grads did exactly as you'd expect -- took the Macs with them into the workplace, and the rest is history for Apple.
If you make the same major bonehead mistake twice, you deserve to die. And die Commodore did. Wonderful technology; lousy marketing.
