I recently had a job interview and one of the questions in the written exam that they gave me was about the new data types in SQL Server 2005.  I did get most of them.  So here are the new data types in SQL Server 2005, in case you wanted to know:

XML

As the name suggests, this data type can store XML data.

VarChar(MAX), NVarChar(MAX), and VarBinary(MAX)

These are called large value data types.  By specifying the MAX keyword in the VarChar, NVarChar, and VarBinary data types, you essentially increased the storage size of these data types to 2^31 - 1 bytes.
