PDC attendees are given a free copy of OneNote
This is pretty cool! I got this in an email yesterday:
“For PDC05, we will be making available the breakout session content available not only as Microsoft PowerPoint files but also as Microsoft Office OneNote® 2003 files. Take notes during presentations the easy way! To help you take advantage of this, Microsoft is offering you one free copy of OneNote 2003-a $99 USD estimated retail value. OneNote is the popular note-taking program for desktops, laptops, or Tablet PCs. Use OneNote at PDC to take notes about the presentations you attend, so that your notes are searchable and easy to share with your friends and colleagues. "
The email contained a link to a download of OneNote and provided a product key for it. Pretty sweet. I already own a couple of licenses of OneNote (it comes with Tablets these days), but this is a neat way to provide the conference material.
