Basically, the Acorn series of hardware was the UK's answer and equivalent to the American Apple Mac educational market!
I should know something about this - unfortunately my area was well behind in computing and I only started using Acorns for the last three years of Primary school.
However, I was still using them in HIGH SCHOOL up until I was about 14. Only then did they replace everything with PCs (at the time I was really thankful, because I was in the mindset that PCs are/were the way to go and that every other platform was obsolete).
Until my primary school had Acorns they were solely using those BBC machines. Now that's nostalgia!!!
