Except that, depending on your browser, it is impossible to navigate to the second slide. In opera mini, the slide itself is not clickable, there are no arrows visible, arrow keys are not available, and the "contents?" link points to a trunkated list starting at slide 15. I'd really like to read the presentation, but it is completely inaccessible.
