I watched an Acorn demo in 1993 and wasn´t terribly impressed. Amiga was far ahead on the user-interface (e.g. It seemed that proportional fonts were a problem for some of the more popular Acorn software). And the idea that some of it really was written in Basic didn´t impress me either.
So if there was something revolutionary about the boxes (except for the raw power of RISC) they did a poor job at communicating it. I don´t think the market would have noticed the benefits of Archimedes & Co.
