title: Advantages of SQL Server 2008 over SQL Server 2005?
body: <p>What are the key differences between Microsoft's SQL Server 2005 and SQL Server 2008?  </p>
  
  <p>Are there any compelling reasons for upgrading (any edition, as I have a customer with multiple editions)? Or is there a website with either a chart or bullet point comparison of the two servers?</p>
  
  <p>Also, is there anything noteworthy in the <a href="http://en.wikipedia.org/wiki/SQL_Server_Express" rel="noreferrer">Express</a> editions of either version?</p>
