They are members of EEA and Schengen area, though.
The EEA implies that many/most(?) of the regulations have to be followed, pay a lot of money for access to the EU free market while having no votes. I think it would be much better for Norway to be member of EU, and I voted so in the last referendum, with the exception of having to use Euro.
Schengen area is for free movement of people inside the area, but have it's own set of rules and regulations to follow.

The border free Schengen Area guarantees free movement to EU citizens, along with non-EU nationals living in the EU or visiting the EU as tourists, exchange students or for business purposes.
