I think the tablet PC is a great personal productivity tool for note taking, but it's greatest benefit will be when businesses introduce them to their sales and service organizations. These professionals are generating tons of paper documents (sales orders, contracts, invoices, etc.). Imagine if they went digital and used their tablet PC to fill out these documents. They could capture the customer's handwritten signature and email the completed documents back to their headquarters via their wireless Internet card. The productivity savings would be in the elimination of faxing, scanning and retyping of data.
