Abstract: A mobile computing device has an operating system that configures the mobile computing device by defining at least one user session, wherein the at least one user session includes a plurality of contexts, each context of the plurality of contexts having separate bindings of input and output resources, and separately managed applications. For example, a different context can be associated with each display device. The operating system is further configured to receive information about applications executed in the separate contexts, to receive information about environmental conditions of the computer, and, to selectively limit operation of applications in each context according to the environmental conditions and the applications executed in both contexts.

Abstract: Systems and methods are disclosed that facilitate minimizing data transfer from a post office protocol (POP) server to a client device by employing a date filter with a predefined date range and applying a message body size threshold above which only a message header will be downloaded to conserve bandwidth and/or memory space on the client device. A user can request download of a message for which only a message header was originally downloaded if the header comprises information of interest to the user.

Abstract: A system that enables notification of a critical quota status related to a mail (or Exchange) server is provided. The system can employ parameters directly from a mail server or, alternatively, from a stats store located within a client device to trigger generation and delivery of a quota full (or exceeded) state. This alert can be locally generated within the client device to convey the critical quota status. In operation, the alert protocol can employ most any protocol including but, not limited to, an email, calendar entry, task, instant message (IM), or the like. In the case of an email alert, the system can timestamp the alert thereby making it always appear on the top of the inbox thus, conspicuous to a user.
