Those of you who have a TabletPC are probably familiar with the built-in note-taking application called Journal. You're probably also confused as to how Microsoft could release two programs (OneNote and Journal), that seem to behave so differently, and don't even interoperate well. The answer to that is everyone else who does not have a TabletPC. Let me explain.
First, if you do not own a TabletPC, you are in the great majority, and you probably don't have many serious complaints about the way ink is supported in OneNote - that's because you don’t have a good way to generate the ink in the first place (yes, you can use an external digitizing tablet, or a mouse or trackball, but these are clearly inferior to just being able to write on the screen where the ink appears, as you would with paper or a TabletPC). The point is that you see OneNote as a great place to type and collect text and images by drag/drop or copy/paste. You can even record audio synced to your typing, manage to-dos and important items with note flags, etc. In short, almost all the features of OneNote work great on a laptop or desktop.
