How I Work: Bill Gates - Apr. 4, 2006:
If you look at this office, there isn't much paper in it. On my desk I have three screens, synchronized to form a single desktop. I can drag items from one screen to the next. Once you have that large display area, you'll never go back, because it has a direct impact on productivity.
The screen on the left has my list of e-mails. On the center screen is usually the specific e-mail I'm reading and responding to. And my browser is on the right-hand screen. This setup gives me the ability to glance and see what new has come in while I'm working on something, and to bring up a link that's related to an e-mail and look at it while the e-mail is still in front of me.
