patoquac, 'tietokone' means 'knowledge machine'.
Finnish words are very literal, for example: Fridge = ice closet, braces = tooth iron, matches = fire sticks, plane = flying machine, umbrella = rain shadow, octopus = ink fish, platypus = water beak animal, bra = breast vest etc.
Helen, yes Tieto is an IT company, and I work in it, though in Lithuania not in Finland :). It's interesting that few years ago the company was called Tieto Enator, where enator goes for some word in Swedish, don't know really. But for lithuanians that sounds weird, like 'Terminator', thus now only Tieto has left.
