I also think my computer is my number one resource.  I use it to find phone numbers, address, make hotel reservations and other info I may need for work or personal use.  I also use Deskdemon as a resource guide to get answers to questions I may have.

I also like the clear plastic folders on my desk.  We have several people in the office who use these folders (they are from our former company) and I like them to keep my desk organized and it looks better.  The rest of the office will just through things on my desk with a paperclip and sometimes the clip comes off.  I have tried to get everyone else to use the folders but they refuse to.

When I working at my old company, I used to make a copy of my boss' calendar on Friday for the next week so if the computers went down (I was in IT so our computers got fixed first), I would have a paper copy to keep my boss  on track. and I would add meetings to this calendar as the week went on.
