In Macworld's post "Hands on with the iPad: First Impressions," the statement is made:
"However, we were sad to discover that presenter notes are not supported by the Keynote app, so if you rely on those notes to guide your presentation, you will be disappointed by this initial version of Keynote."
I can only hope presenter notes will be added in a later version. The mere idea of printing out my notes seems like such a step backwards.
