Why:

Some appliances (like TVs, for instance) have a "hot chassis", i.e. the
chassis is not isolated from the power line. Given this, it's better that
the chassis be attached to the neutral wire than the hot wire. Polarized
plugs decide this for you.

A flat file and a minute or two will allow you to exercise your God-given
right to plug things in backwards.
