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. The 770 is bundled with applications including the Opera web browser, Macromedia Flash and Gizmo. A critical bug has been identified that 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 ; preferably before having used the WLAN connection for the first time.
Versatility
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 permits enthusiasts to expand their tablets to include USB mass storage, Bluetooth GPS receivers, a normal USB keyboard, or other devices.
Criticism
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. Short battery life 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 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.
