To me, the irony about the Facit story is hearing about the Facit engineers, who had bought cheap, small electronic calculators in Japan that they used to double-check their calculators.
Per a mi, la ironia  de la història de Facit va ser enterarme que els seus enginyers van comprar al Japó calculadores  electròniques, barates i petites que utilitzaven per tornar a revisar les seves calculadores.
