Alex,
It is not "scientific" to say that a theory is correct just because it is popular or useful. Scientifically Newton's Law *has* been replaced by Einstein's theory. That Newton's law is more comfortable or popular in 2004 and is accurate enough for school children, does not make it valid.
Don't forget that Creationism is popular too!
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
