81% of OneNote users preferred using OneNote 2003 vs 19% who preferred using OneNote 2007 Beta.  I am not surprised of these results.  Until recently, OneNote 2007 was in a closed beta and most OneNote users did not have access to it.  However, now OneNote 2007 is a public beta, I wonder if the results would be the same.  Look for a similar poll in a month or so.
