Do Muslims have to learn the Qur'an off by heart?

Musilms dont NEED to learn it off by heart,but it is still importent,yet the muslims need to know the meaning and know about it,and should be able to atleaste read it by looking,i don't see the point of learning the 'Surahs' off by heart,only what is to be performed in Namaz(Prayer!)-My opinion,I am also going to be muslim :)
