Kids know how things should work

Today I learned that Kids know how things should work. Today the Little Boy was using a cellphone (yes the 4 year old was using a cellphone, don't pretend like you haven't handed one to your youngin' )and he wanted to show the person he was talking too what he just got, so he pointed the phone at the object and and said "See". Now Really thiw is how it should work. It's 2005 we don't have cars that fly, so we should at least have cellphones that have video conferencing built in.
