Single Biggest Issue with Logitech Performance MX over MX Revolution

The lack of the side scrolling button. I used it for page up/page down universally and the two arrow keys above and below it were used for various things: back/forward in Safari, delete and go to next/previous unread in Entourage and Cyndicate, etc.
The number of buttons I've got has been reduced by two, and I don't like it. There's no easy way to replace page up/down and scrolling may take a lot of getting used to.
