Amiga (any platform) is not suited for professional work, missing components like 64bit, memory protection or multicore support are the least problem, more problematic is missing drivers for 3rd party hardware like printers and expecially no up-to-date software. I would never even guess to use amigas for professional work, it is a nice hobby I waste some time on when I have some time left, not more not less.
None of that was a problem for me when I did my school and college assignments on my A1200 in the late 90's. I used Wordworth, and the structured drawing tools were fantastic and the resulting prints professional in my opinion.
