Nokia 770
The Nokia 770 was the first internet tablet from Nokia and was presented on 25 May 2005 at the LinuxWorld Summit in New York. A launch was originally scheduled for the third quarter of 2005 and even after Nokia repeatedly increased its production capacity, it was after the actual release date (November 1, 2005) for several months a longer delivery time than 4 weeks.
The Nokia 770 was the last to buy for € 349 at Nokia, but is now no longer available.
The touch-screen display ( 4.13 " diagonal) has a resolution of 800 × 480 pixels, which due to the small form factor ( 90 mm × 55 mm) is a very high resolution (225 pixels per inch). The device weighs 185 g, with upper shell 230 g The USB connector is equipped with an on- the-go functionality serve with the N770 as a USB host, but can provide no USB devices with power.
After Nokia's information, the device with full battery 3 hours at intense ( WLAN ) use or 7 days in standby mode can operate, but experience has shown a significantly longer duration. From the standby mode, you get in a split second in the normal operation mode (Instant -On ).
Nokia N800
In January 2007, was presented in Las Vegas with the N800 the successor of the first Nokia Internet Tablets at CES 2007.
New compared to the 770 was one of the OMAP -2420 microprocessor and twice as much labor and mass storage. The CPU clock is 333MHz at delivery, but increases with the firmware update to the 2008 platform at 400 MHz.
The N800 has an internal and external SDHC memory card slot, so you can use through appropriate adapter card, SD, MicroSD, MiniSD, MMC, and RS- MMS memory cards. In addition, it has a built-in webcam, Bluetooth 2.0 and stereo speakers. The actual bundled operating system Internet Tablet Edition 2007, based on Maemo 3.0, a customized version of Linux for embedded devices. The successor version of Internet Tablet 2008 Edition can be installed via firmware update also.
The N800 was available on the first day of sale at the Nokia Online Store at a price of 399 euros, now it is no longer available.
Nokia N810
On 17 October 2007, Nokia announced the model N810 Internet Tablet. It is based on the OS2008 - platform ( Maemo 4.0 Chinook, also on the N800 installable). Although somewhat smaller than its predecessor, it also offers a GPS receiver and a slide out QWERTY keyboard (the device for the German -speaking world have a QWERTY keyboard ). The CPU of the N810 clocked at 400 MHz faster than its predecessor on delivery.
The display size has not changed, but it is now running transflective and therefore easy to read even in sunlight. According to the manufacturer, the device should have higher battery life. Support for MMC memory cards has been discontinued, in addition it has only one ( external ) card slot for mini or microSD (HC ) memory cards (microSD miniSD via adapter). Instead of the internal memory card reader of the N800, the N810 has a built- two gigabytes of internal flash memory. The FM radio has also been omitted. From the mini-USB port, a microUSB port has become. The camera is built directly into the case, instead of the N800 folds out to the left.
It may since mid-November 2007 in the U.S. for 479 USD (excluding taxes ), are available for purchase in Germany for 449 Euros. On the software side, the Opera browser has been replaced by a free Mozilla browser and the GPS feature is complemented by its own navigation software.
Nokia N810w
This WiMAX -enabled device was announced on 1 April 2008 at CTIA in Las Vegas. It is based on the Nokia N810. Up to 4 grams more weight and WiMAX support ( IEEE 802.16e standard), no differences for N810 are known. The device is no longer produced.
Nokia N900
End of August 2009, Nokia announced the N900 successor. Early December, the first production run were delivered in Germany. The N900 for the first time includes a telephone function. It also features a 5 megapixel camera and 32 GB of flash memory, and a CPU ARM Cortex -A8 architecture, which is clocked at 600 MHz. By reducing the screen size to 3.5 " it is smaller and lighter than their predecessors.
GPS navigation
For the 770 and N800 customized GPS navigation sets are offered. The N810x models and the N900 have already built a stand-alone GPS module. In addition, the N900 may change its position with the help of GSM positioning determine (eg, when GPS reception is not possible ), which is due to the system significantly less accurate.
Software
The special feature of the Nokia Internet Tablets is largely free firmware Maemo. Maemo is based on the Debian Project, the X11, GTK and D-Bus. Through this approach Maemo can concentrate many external resources, and the porting effort for further software is low.
As the central point for the firmware development Nokia has launched the Maemo project to life, which is the official development platform for software and provides developers with documentation and all other development tools.
Nokia has taken in advance of the development of several open source developers under contract and paid them for the work on their own projects. Many of the developments in the various projects have also been incorporated into the original versions of each software.
There are more than a hundred well-known open - source programs ported to Maemo, which is very simple, as Nokia focuses on established standards in the open source environment. Caused a sensation in the successful porting of Doom 1 on the unit. There is software for GPS navigation, e -book reader, PIM management, and a text-to- speech program.
Preinstalled are sorted by Maemo version in addition to free software also purchased from Nokia Opera web browser, a video player based on the Helix engine, as well as handwriting recognition used.

Internet Tablet OS 2006
On 28 June 2006, Nokia released the first major update for the firmware Internet Tablet OS 2006 Edition Maemo 2.0 respectively. Additions are instant messaging or VoIP capabilities that are based on the open standard XMPP / Jabber or its extension jingle and sponsored by Google Talk. Also, add-on software is now delivered via a front-end for APT to the end user, which makes installing and updating a breeze. Internally, most of the software has been updated by users is a subjectively faster response time reports. As requested by users feature a full-screen software keyboard was implemented.
Since 13 July 2006, the Gizmo5 software is available in a version for the Nokia 770, which was created in collaboration with Nokia.
Internet Tablet OS 2007
Based on maemo 3.x Bora and is used in the Nokia N800.
Internet Tablet OS 2008
Based on maemo 4.x Chinook and the Nokia N800 and Nokia N810 used. Among the visible changes from the previous version include a new, Gecko -based web browser, and support for the Bluetooth Headset Profile HSP. On the Nokia N800 with this operating system version of the 400 MHz processor is throttled no longer on 333 MHz.
Navigation Software
The three Internet Tablets are also suitable as a navigation device when you install the appropriate navigation software. In addition to a commercial solution that is sold by Nokia, there is the open source projects Maemo Mapper and Navit. Both applications allow storing map data on the memory card, so no internet connection is required when operating as a navigation device.
The most important difference between these two programs is the type of data. Maemo Mapper uses this image data, for example, OpenStreetMap or Google Maps, while Navit uses vector data from OpenStreetMap. Therefore Navit has the advantage to be able to calculate the routes offline, while Maemo Mapper this takes up a server service on the Internet. Another advantage of using vector data is the significantly smaller file size, which is currently only around 120 MB for a full map of the whole of Germany, instead of about 80 GB for the same data in the form of image files. An important disadvantage of the use of vector data that is required to render a lot of computing capacity and battery power. Therefore, based on vector data representation is usually poorer than the detail of pre-rendered maps.
Others
Target group
Since the device according to analysts has no direct competition, it is more successful as a niche product, as Nokia expected. It is not in competition with Microsoft and Intel's Ultra -Mobile PCs, as they are larger and located in a very much higher price segment.
According to Ari Jaaksi ( Nokia Open Source commissioner ) be the class of device, the Nokia 770 marks out, in comparison to the PC as the phone compared to traditional stationary phone. He sees a distinct advantage of the device is that it is not a complete mobile phone and be perfectly complemented with this, which can be replaced independently of the N770.
Developer program
Nokia offered 500 software developers who had demonstrably used for the open - source community, the opportunity to purchase the device before the official launch at a price of 99 € to develop software for it. The proceeds from this sale Nokia donated directly to the GNOME Foundation.
