The abacus and the slide rule have both been replaced by new technology. When I went to school electronic calculators with scientific notation were becomming available. These days, in Norway, kids are at some point expected to have graphing calculator, but isn't this an anachronism?
With desktop and laptop computers have we have access to tools like Matlab, Mathematica, Macsyma and Gnu Octave. And schools are beginning to use tablet computers. Isn't the natural consequence that calculators go away, and that tablet computers take over the role of both the standard computer and the calculator. Maybe the concept of the Dynabook is eventually becomming a reality?
Currently, the rules in the Norwegian educational system rules out tablets, but there is time for a change, don't you think?
