In this paper I describe the Associative PDA 2.0, a mobile system for Personal Information Management (PIM), based on an associative information network. In addition to associate items manually, context information is used for defining associations and thereby indexing data automatically. The design is limited to note-taking, allowing a representative example of a PIM application. I conducted initial interviews to receive background information about note-taking. The system will be evolved following a user centered design. It will be evaluated in a longterm study with authentic personal information to verify the design and usefulness.
