Methods and systems to predictively determine to perform a computing activity based on contextual information. Context-based criteria are defined based relationships between user-computing activity and contextual information, and are evaluated based on updated contextual information to determine whether to perform the computing activity. Context-based criteria may be defined to predictively identify content to be transferred/synchronized/updated and/or deleted, and/or to select one or more of multiple devices to receive content. Content may be selectively synchronized across devices of a user and/or shared with another user(s). Context-based criteria may relate to, without limitation, location, activity, computer-usage patterns, motion, and/or schedule of a user, device location, user/device proximity, relationships amongst content, users, and/or devices. Context-based computing environment parameters may be provided to pre-loaded content on device (e.g., store, open, and/or configure an operating system, application, and/or resource), with little or no user interaction.
