Nokia Internet Tablet
Nokia Internet Tablets was the name for a series of small mobile computers from Nokia that came onto the market from 2005. The N7xx and N8xx models can be classified between PDA and Ultra-Mobile PC , while the much smaller N900 is more of a smartphone and is classified by Nokia in the NSeries .
As the generic name suggests, they were primarily intended for mobile Internet use. To this end, they have a full web browser, software for e-mail processing, a Feed Reader , and PDF -Reader, audio, image and video applications. In contrast to other portable Linux devices, a full Linux distribution and no restrictive embedded variant is used, so the Nokia 770 was traded as the unofficial Zaurus successor when it was released .

Nokia 770
The Nokia 770 was Nokia's first internet tablet and was presented on May 25, 2005 at the LinuxWorld Summit in New York . A market launch was originally planned for the third quarter of 2005 and even after Nokia had increased production capacities several times, there was a delivery time longer than 4 weeks for several months after the actual release date (November 1, 2005).
The Nokia 770 was last available for € 349 from Nokia.
The touchscreen display (4.13 ″ diagonal) has a resolution of 800 × 480 pixels, which is very high-resolution (225 pixels per inch ) due to the small form factor (90 mm × 55 mm ). The device weighs 185 g, with the upper shell 230 g. The USB connection has an on-the-go functionality with which the N770 can also serve as a USB host, but cannot supply USB devices with power.
According to Nokia's information, the device can be operated with a full battery for 3 hours with intensive (WLAN) use or 7 days in standby mode, but experience shows a significantly longer runtime. From standby mode you can switch to normal operating mode ( Instant-On ) in a fraction of a second .
Nokia N800
In January 2007, the successor to the first Nokia Internet tablet, the N800, was presented at the CES 2007 in Las Vegas .
New compared to the 770 was the OMAP -2420 microprocessor and twice as much work and mass storage. The CPU clock is 333 MHz on delivery, but was increased to 400 MHz with a firmware update to the 2008 platform.
The N800 has an internal and external SDHC memory card slot, which is why you can also use SD, microSD , MiniSD, MMC and RS-MMS memory cards with suitable adapter cards . It also has a built-in webcam , Bluetooth 2.0 and stereo speakers. The operating system supplied is Internet Tablet 2007 Edition , based on Maemo 3.0, an adapted Linux version for embedded devices. The successor version Internet Tablet 2008 Edition can also be installed via firmware update.
The N800 was available on the first day of sale in the Nokia online shop at a price of 399 euros.
Nokia N810
On October 17, 2007, Nokia announced the N810 Internet Tablet . It is based on the OS2008 platform (Maemo 4.0, Chinook, can also be installed on the N800). Although a little smaller than its predecessor, it also offers a GPS receiver and a sliding QWERTY keyboard (the devices for the German-speaking area have a QWERTZ keyboard ). The CPU of the N810 now clocks at 400 MHz instead of the original 333 MHz of the predecessor.
The screen size has not changed, but it is now transreflective and therefore easy to read in sunlight. According to the manufacturer, the device should have a longer battery life. Support for MMC memory cards has been discontinued, and there is only one (external) card slot for mini or microSD (HC) memory cards (microSD via miniSD adapter). Instead of the internal memory card reader of the N800, the N810 has a built-in two gigabyte internal flash memory . The FM radio has also been omitted. The miniUSB connection has become a microUSB connection. The camera is built directly into the housing, instead of being folded out on the left side as with the N800.
The device was available to buy from mid-November 2007 in the USA for USD 479 (excluding taxes) and in Germany for EUR 449. On the software side, the Opera browser has been replaced by a free Mozilla browser, and the GPS function has been supplemented by its own navigation software.
Nokia N810w
This WiMAX enabled device was announced on April 1st, 2008 at the CTIA in Las Vegas. It is based on the Nokia N810. Except for 4 grams more weight and the WiMAX support (according to IEEE 802.16e standard), no differences to the N810 are known.
Nokia N900
At the end of August 2009, Nokia announced the successor N900, the first device with telephone functionality. The first series devices were delivered in Germany at the beginning of December. The device has a 5 megapixel camera, 32 GB flash memory and an ARM CPU (Cortex-A8) with a clock rate of 600 MHz. By reducing the screen diagonal to 3.5 ", it is smaller and lighter than its predecessor.
Adapted GPS navigation sets were offered for the 770 and N800. The N810x models and the N900 already have an integrated GPS module. In addition, the N900 can determine its position with the help of GSM positioning (e.g. if GPS reception is not possible), which is significantly less accurate due to the system.
software
The special feature of Nokia Internet Tablets is the largely free firmware Maemo . Maemo is based on the Debian project, the X11 , GTK + and D-Bus . This approach allows Maemo to concentrate a large number of external resources, and the effort to port further software is minimal.
As a central point of contact for firmware development, Nokia launched the Maemo project, which is the official developer platform for the software and provides developers with documentation and all development tools.
Nokia has contracted several open source developers in advance of development and pays them to work on their own projects. Many of the further developments in the various projects were also adopted in the original versions of the respective software.
More than a hundred well-known open source programs have been ported to Maemo, which is very easy because Nokia relies on established standards in the open source environment. The successful porting of Doom 1 to the device caused a stir . There is software for GPS navigation, e-book readers, PIM management and a text-to-speech program.
Depending on the Maemo version, the Opera web browser purchased from Nokia , a video player based on the Helix engine and handwriting recognition are preinstalled, as well as free software .

Internet Tablet OS 2006
On June 28, 2006, Nokia released the first major update to the firmware as Internet Tablet 2006 Edition or Maemo 2.0 . Added to this are instant messaging and VoIP functions based on the free XMPP / Jabber standard or its extension Jingle and sponsored by Google Talk . Additional software is now also delivered to the end user via a front end for APT , which makes installation and updating very easy. Most of the software has been updated internally, and users report subjectively faster response times. A full-screen software keyboard was implemented as a function requested by users.
From July 13, 2006 the software Gizmo5 was offered in a version for the Nokia 770, which was developed with the cooperation of Nokia.
Internet Tablet OS 2007
Based on maemo 3.x Bora and used in the Nokia N800.
Internet Tablet OS 2008
Based on maemo 4.x Chinook and used in the Nokia N800 and Nokia N810. The visible innovations compared to the previous version include a new, Gecko -based web browser and support for the Bluetooth headset profile HSP. With this version of the operating system on the Nokia N800, the 400 MHz processor is no longer throttled to 333 MHz.
The three internet tablets can also be used as navigation devices if the appropriate navigation software is installed. In addition to a commercial solution that is distributed by Nokia, there are the open source projects Maemo Mapper and Navit. Both applications allow the storage of map data on memory cards, so that no internet connection is necessary when operating as a navigation device.
The main difference between these two programs is the type of data. Maemo Mapper uses image data from, for example, OpenStreetMap or Google Maps, while Navit uses vector data from OpenStreetMap. Navit therefore has the advantage of being able to calculate the routes without an Internet connection ("offline"), while Maemo Mapper uses a server service on the Internet for this. Another advantage of using vector data is the significantly lower storage requirement of currently only around 120 MB for a whole map of all of Germany, instead of over 80 GB for the same data in the form of image files. An important disadvantage of using vector data is that rendering requires a lot of computing capacity and thus battery power. Therefore, the representation based on vector data is usually less detailed than that of pre-rendered maps.
Others
target group
Since the device has no direct competition, according to analysts, it is more successful as a niche product than Nokia expected. It does not compete with Microsoft and Intel's ultra-mobile PCs , as these are larger and in a much higher price segment.
According to Ari Jaaksi (Nokia's Open Source Officer), the device class that defines the Nokia 770 compared to the PC is like the cell phone compared to the traditional stationary phone . He sees a decisive advantage of the device in the fact that it is not a complete mobile phone and that it perfectly complements this, which can be exchanged independently of the N770.
Developer program
Nokia offered 500 software developers with a proven track record of advocating the open source community the opportunity to purchase the device for € 99 before it officially went on sale to develop software for it. Nokia donated the proceeds from this sale directly to the GNOME Foundation .
