Support your technology

Yet another story in the press recently referred to a vehicle driver following his (it usually is a man, isn't it?) satnav instructions into some form of disaster.

Two lessons from this .... firstly, old technology often does the job well enough (and more cheaply) .... secondly, engage your brain along with your technology ... if you don't have a 'feel' for the results you expect (such as when doing your sums on a calculator), you don't know when things are going wrong.
