My Treo 700w has become a perfect compliment to my work laptop. For better or worse, my Treo has become an intregal part of how I do business. It works (usually seamlessly) with my Microsoft Outlook and calendar (My phone vibrates 15 minutes prior to all of my meetings). My Outlook contact list (and all of those phone numbers!) are instantly transferred into the phone's contact list- it really has revolutionized the way I organize all of my business trips! On a trip I list all of my visits, agendas, contacts and directions into my Outlook account and presto they are linked straight into the Treo and available to me while I am on the road.
