I don't use phpmyadmin, but I assume that it would like to use the
primary key to make sensible select/update-statements. Apart from
that, it is just an advice for your own good.
Primary keys are to ensure integrity, but you get performance gains as
an added bonus, because you get the table indexed. In other words,
without a primary key (when applicable), you risk making a mess of
your data and having a crappy performance. But the choice is still up
to you. :)
