"Ordinary information managers are like data warehouses where information just piles up. A Personal Information Processor is like a data factory where lots of workers help to process raw data into a more valuable product. Smart Folders represent the workers in the Zoot 4.0 data factory.", said Tom Davis, president of Zoot Software. (I think Tom is Zoot Software.)
