Jim Blizzard has discoveredOneNote.

I installed OneNote as part of the Office 2003 Beta 1 release, not knowing too muchabout it. That was about 3 months ago. Now (especially since Beta 2), OneNote is handsdown my favorite Office application. I tend to be a somewhat disorganized person,at least when it comes down to keeping track of meeting notes. Usually,whenever I have to jot something down I'll just fire up Word and save asmall file off to a random corner of my hard drive -- and usually lose trackof it.

OneNote changes all that. It gives me a centralized place to stick all mynotes. There's a rich organizational model -- tabs across the top of the screenlet me organize notes into broad categories. Tabs on the side of page let groupideas within those categories.

I love the way I have the freedom to type notes anywhere on the page. It'sreally easily to pick up text and move it anywhere on the page, so I can organizemy notes visually in the page. This is notoriously hard to do in Word. 

I can also flag note items with a number of different visual flags,and then search my notebook to pull out items flagged with a specific flag. So,if I have a ToDo item, I can flag it as such -- and it shows up in OneNote'ssidebar as a ToDo and can also be sent to me as an Outlook task. That's pretty sweet.

There's support for Ink and handwriting recognition, of course, but since I don'thave a TabletPC I don't make too much use of that. But, this is single applicationthat could convince me to buy one -- OneNote is the killer app for the TabletPC.
