Just jumping in, because Matt's baited me a bit.

You need to understand that although a clustered index is put on the primary key of a table by default, that the two concepts are separate and should be considered separately. A CIX indicates the way that the data is stored and referred to by NCIXs, whereas the PK provides a uniqueness for each row to satisfy the LOGICAL requirements of a table.

A table without a CIX is just a Heap. A table without a PK is often considered "not a table". It's best to get an understanding of both the PK and CIX concepts separately so that you can make sensible decisions in database design.
