Well I am a firm believer in that a few errors are not going to be that big of a deal.
Have you ever seen that experiament when they mix up the letter in the midlde of the wrod and nodoby notcies becusae the mind knows what is being said and corrects it automtacilly.
Well I truly believe in that
I can scan a 400 page book into my mac within 30 min, so that is why I have no issues doing it.
