Abstract: Systems and methods for establishing and maintaining a shared browsing experience are disclosed. A method for establishing a shared browsing experience includes an inviter computer communicating to an invitee computer, via an online messenger communication path,an invitation to establish a co-browsing experience. The invitee computer communicates to the inviter computer, via the first communication path, an acceptance of the invitation. A co-browsing communication path is then established between the inviter computer and the invitee computer. Information relating to the shared browsing experience is then communicated between the inviter and invitee computers via the co-browsing communication path.

Abstract: An extensible device synchronization architecture and user interface is provided. A variety of device classes are supported, and support is also provided for mass storage, WMDM, MTP, AS, etc. An extensible UI model is provided that allows content type specific setting UI to plug-in. Support for 2-way synchronization is also provided. The synchronization architecture includes a content type user experience level, and a synchronization engine layer, with handlers and a synchronization engine API which handlers can use to manage their item level synchronization relationships and implement the semantics of the synchronization. In addition, the content that is being synchronized may be transformed so that the user's experience on the destination device (e.g., mobile phone, portable audio player, PDA, other type of personal or handheld computer, etc.) is optimized and these transforms are also extensible.

Abstract: System and methods for managing content on a media device such as a portable digital audio device are described. The system recognizes when a digital audio device is connected to a computer and it automatically notifies a user that the audio device is connected and provides an entry point through which content of the audio device can be managed. The audio device is presented in an extended namespace (UI extension) of an operating system user interface in the same manner that typical storage devices (e.g., hard drives and floppy drives) are presented by the operating system user interface. Contents (e.g., music files) of the audio device are manageable through the UI extension in the same familiar manner as the contents of other typical storage devices of the computer.

Abstract: Methods, systems, and computer program products for tracking real-time communication data within a single contact tracking application for diverse communication providers and applications. A global data store is synchronized with real-time communication data, such as presence, status, unread messages, and unread notifications, from each application/provider. Real-time communication data for contacts dynamically determined to be recent contacts is retrieved from the data store, based on properties such as a most recent communication time, a communication count, and the like. Real-time communication data corresponding to contacts identified as pinned contacts for which display of real-time communication data is preferred, also may be retrieved. A user interface is generated for displaying the one or more recent and/or pinned contacts, which may vary in size based on the number of contacts identified as pinned contacts, from which a contact may be selected for real-time conversation or e-mail.
