I have books on math from encyclopedias from parents from the 80's weighting more than 4 KG each.
Now I can just fire up a browser and understand a hard math concept in minutes in a much easier way. With free as in freedom CAS tools and such, and with a netbook bought at a ridiculous price 20x cheaper than the book volume set itself,
which back in the day costed A LOT.
