Wow, that's some news there! How can you not like identity columns? I tell database developpers to put 1 on each and every table in the database. Only in really really rare scenarios we don't put an identity column.

What's your sight on this? It puts an easy uniqueness to the rows for transmitting to another server, it's a perfect field for the update statements, and so is it for the delete. What's so wrong with it?
