I don't know why but I always love these articles to see how other people use software and I would love to be a fly on the wall in Bill's office but since I can't I can read this article:

Office Hours: How Bill Gates uses Office

In particular I love this quote:

I always take a lot of notes about ideas to think about or things to follow up on. I try to bring my Tablet PC to meetings as often as possible so that I can use OneNote 2007 to write notes in ink that can later be searched or converted to text. Even if I forget my Tablet, I can scan a document or piece of paper and add that image to OneNote. One of the nice new features in OneNote 2007 is that it automatically recognizes the text in those scanned documents, so that it's easy to search for them later.

Just cool to see how he uses OneNote and the rest of the products in the Office system, check it out!
