you never read the book, which has named the apple notebooks and some shareware software (product placements which are almost gone by now). The main character(s) explicitly saved up for the given machine (although the movie isn't accurate down to the model)
the books all had this odd habit of being very specific about brands--Lisbeth's favorite microwave pizza, her computers, i think even the names of the ikea furniture. idk if that's normal in swedish writing or if it was just larsson....
