You can find the slides from the PDO talk here.
While I'm here talking about PDO, I wanted to give you a heads up. PDO 1.0RC2 will move from PDO_XXX style constants to using class based constants like PDO::XXX. The reason for this change is that it will fit in with namespace support in PHP when it is implemented.
Yes, this should have been changed before 1.0RC1: Sorry.
This change has not yet been made to the packages available via PECL, but is present in the PHP 5.1 branch--including PHP 5.1RC3.
