Aside from the computer, as you say in your lead...I guess I'd have to say my phone. I've got it programmed to hold all my international contacts with speed dials, and can use it to page people. I use it for teleconference meetings by hooking up the speaker portion and just listening in while I continue to work.
I forward important messages I receive from customers to the appropriate sales people or managers. I've programmed in the express shipping company numbers, as well as other vendors.
I'm sure our phone system isn't the most current available, but it's got quite a few handy features, such as internal digital advisories for OUT OF THE OFFICE or IN A MEETING, etc.
