Abstract: Methods and systems provide the wireless use of a desktop computer through a lightweight long-range mobile computing device with extended battery life and no writeable or user-accessible persistent data storage, such as a hard drive, which could be detrimental if lost. In one implementation, the light-weight mobile computing does not run a full operating system, thereby reducing overhead and increasing speed. The mobile computing device provides mobility while providing access to information on a desktop computer. Since some components of conventional laptops are not needed, it may be smaller and/or have lighter weight, and provide extended battery life, while providing greater security by avoiding the risk of data loss. These systems provide a lightweight mobile wireless KVM device (e.g., a small “notebook” computing device) to connect to desktop computers. These lightweight, mobile computing devices may provide “instant on” capabilities avoiding the start up time of normal laptop computers.
