Maybe I should rename me to Quijote, switch back to pen and paper and
should start to raise carrier pigeons. ;)

E.g. my parents are stull successfully using contact lists on paper. 
These are still more readable, easier to handle and smaller than any 
available electronic replacement. And they have absolutely no problem to 
destroy an old one when they replace it with a new one.
