MSFT made a preview of OneNote 2003 SP1 available yesterday.
In addition to being able to “Record video notes”, there are a number of other niceties too — like for example inserting documents from other Office programs into OneNote and the ability to share OneNote sessions in real time.
IMHO, OneNote is a wonderful environment for aggregating and now sharing disparate information.
Yet, there’s still no mention of MSFT opening the file format.
