You'll probably enjoy "Ruthless: The Story of Amstrad and Alan Sugar in the 80's and 90's" (https://www.youtube.com/watch?v=eiIXn9Tr5hI), an absorbing video that offers some opinionated explanations for the CPC's lukewarm performance in Britain and its success in other parts of Europe. While both the machine and the man were less loved, Sugar did of course have the last laugh as he ended up owning the Spectrum business.

Spectrum fan here, but I do love the CPC's eye popping colours :)
