N800 allows the user to browse the Internet and communicate using Wi-Fi networks or with mobile phone via Bluetooth.

It includes FM and Internet radio, an RSS news reader, image viewer and a media player for audio and video files.

The N800, like all Nokia Internet Tablets, runs Maemo, which is similar to many handheld operating systems, and provides a "Home" screen—the central point from which all applications and settings are accessed.

The Home screen is divided into areas for launching applications, a menu bar, and a large customisable area that can display information such as an RSS reader, Internet radio player, and Google search box for example.

The N800 is bundled with several applications including the Mozilla-based MicroB browser, Macromedia Flash, Gizmo, and Skype.
