The Nokia 770 Internet tablet is a wireless Internet appliance from Nokia, originally announced at the LinuxWorld Summit in New York City on 25 May 2005. It is designed for wireless Internet browsing and e-mail functions and includes software such as Internet radio, an RSS news reader, ebook reader, image viewer and media players for selected types of media.
The device went on sale in Europe on 3 November 2005, at a suggested retail price of €349 to €369 (£245 in the United Kingdom). In the United States, the device became available for purchase through Nokia USA's web site on 14 November 2005 for $359.99. On 8 January 2007, Nokia announced the Nokia N800, the successor to the 770. In July 2007, the price for the Nokia 770 fell to under USD 150 / EUR 150 / GBP 100.

The device was manufactured in Estonia and Germany.
The 770, 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. Maemo is a modified version of Debian.
A critical bug has been identified which causes memory corruption when using the WLAN connection. This could result in system instability and data corruption. Owners of the 770 are encouraged to apply the bugfix; preferably before having used the WLAN connection for the first time.
In October 2006, Nokia released the Navigation Kit for Nokia 770 Internet Tablet. It includes a Bluetooth-based Nokia LD-3W GPS receiver, navigation software from Navicore with maps of Europe, a memory card, a car holder and a car charger. This device supports dual voltage (1.8/3 V) and single voltage (3 V) reduced-size MultiMediaCards. It is compatible with the supplied Nokia connectivity cable DKE-2 (USB), the USB cable to transfer files to the memory card, and is compliant with Bluetooth Specification 1.2 supporting the following profiles: Dial-Up Networking, File Transfer/Object Exchange, Generic Access, SIM Access, and Serial Port.

Because of the Linux-based operating system and the open-source contributions from Nokia, the Nokia 770 Internet Tablet has a great appeal to the hacker and DIY markets. Programmers are porting applications to the Maemo platform allowing a much more rapidly growing application catalog than other mobile platforms would enjoy. The inclusion of Wi-Fi, Bluetooth, and USB host functionality (through a hack) permits enthusiasts to expand their tablets to include USB mass storage, Bluetooth GPS receivers, a normal USB keyboard, or other devices.
The Nokia 770 has received criticism from some technology reviewers. The most common complaint was about the overall speed of the system, due to the relatively slow CPU and the size of the on-board memory (64 MiB). Short battery life (less than 4 hours in the case of continuous Wi-Fi usage) was also a concern. Some reviews suggested problems with the handwriting recognition, and some said tapping the on-screen keyboard was too slow.
Another common complaint was that it lacked the functions of a mobile PDA, although there are now several PIM options created by the community. Also, for Internet access away from Wi-Fi hotspots, the Nokia 770 relies upon a Bluetooth 1.2 phone acting as a modem, and not all bluetooth phones will work with the tablet. Additionally some complained that the device used Reduced-Size MMC (RS-MMC or Micro-MMC) cards that were originally difficult to find. However, the format has since been used in other products and has become widely available. The device originally could only use cards up to 1 GB, but 2 GB cards are supported with the current version of the operating system.
