 There are two big markets . There is the hobbyist and the man in the street . The hobbyist was a dead certainty . We knew we could sell to him because we have so much experience of it and we were offering a better product . The much less certain prospect was the man in the street . There the view was that if we offered him a computer plus a self @-@ training book at a keen enough price he would buy by mail order – which , of course , he has .
