I had a .NET users group meeting tonight with the Northwest Ohio .NET Users group.  I always take my tablet there to take notes in Microsoft OneNote.  Everyone there is taking notes with either their pen and paper or a traditional laptop.  Here is why notetaking on a tablet is better than those two alternatives:

Notetaking on a tablet is better than a paper and pen because you are able to do more than just notetaking.  I was able to check my email, add my time I spent for my client work in a time tracking application, and check out some links that were given to me from the presentation I was at right away.  Also, all the notes that I took are all searchable electronically.  A lot more powerful than just a paper and pen.

You could do all this by typing your notes using a tradional notebook with the same powerful options as a tablet.  One difference is that there is no barrier.  When the presenter was looking into the crowd, there was no barrier between him and I like a screen from a laptop would provide.  This allows you to concentrate more on the presentaton and less on the tool your using to take notes.
