What is a notable feature of RESTlets that benefits end users?

The notable feature of RESTlets that benefits end users is their mobile accessibility. RESTlets are built to allow integration with other applications, including mobile devices, enabling users to access and interact with NetSuite data from anywhere. This mobility enhances the user experience, as it facilitates the utilization of NetSuite's functionalities on various mobile platforms, making it convenient for users to manage their tasks even when they are away from their desktops.

While RESTlets can perform multiple operations, which is certainly a useful function, it is the mobile accessibility that stands out as a direct benefit to end users, allowing for flexibility and improved productivity in their workflows. The other options, while important, do not specifically highlight the usability advantage that comes from being able to access and use NetSuite functionalities on mobile devices.
