The comment about Acorn being a 'Week' company does fly in the face of the facts.
They conceived and developed a RISC processor (ARM was spun off later), this is a feat that defeated *EVERY* other maunfacturer. I also own an IBM RT6150, the worlds first RISC computer with over 100 instructions. IBM (a Strong company?) spent more money on this one project than all of the Acorn markplace spent on all of the kit and software since it's inception.
The education marketplace is still *The* marketplace, how many times have I had to convince people that there are other computers on the market?, this is solely due to the strancle hold that MS has on that market place and the first contact the people have with IT. It is also why MS are willing to spend millions on setting up an IT lab for Oxford University FOC.
Finally, it is not in anyones interest to rake over the coals of the long deceased Acorn, particualrly when what killed it was the General Publics and Governments increasing ignorance of British IT innovation. The Governments neglect of backing up our inventions internationally is killing it stone dead. People like Dyson have to take Hoover to court in the US, at their own expense, because of this failing. How many features of RISCOS have found their way into other peoples OS's?
