The Nokia N900 is a mobile Internet device and smartphone, from Nokia  based on the Maemo  platform, superseding the N810. It runs Maemo 5 Linux as its default operating system and is the first Nokia device based upon the TI OMAP3 microprocessor with the ARM Cortex-A8 core. Unlike the Internet Tablets preceding it, the Nokia N900 is the first Maemo device to include phone functionality (quad-band GSM and 3G UMTS). It functions as a 5 mega pixel camera, a portable media player, and a mobile Internet device with email and full web browsing. It was launched at Nokia World on September 2, 2009 and was released on November 11, 2009 in the United States and 9 European countries.

The Nokia 5800 XpressMusic is a smartphone  and portable entertainment device by Nokia.[4]  It was introduced on October 2, 2008[5]  and released on November 27, 2008.[6]  Code-named “Tube”, it is the first touchscreen-equipped S60 device by Nokia. It’s part of the XpressMusic series of phones, which emphasizes music and multimedia playback. The touchscreen features tactile feedback (though it does not use Nokia’s Haptikos technology.)[7].

The 5800 has a compatibility mode for Java applications that are not touchscreen-aware. It works by using part of the screen for displaying the essential buttons required by the program.

On January 23, 2009, Nokia announced it had shipped the millionth 5800 XpressMusic device, even though it still had not been fully released worldwide.[8] In Nokia’s Q1 report released on April 16, 2009 it was announced they had shipped 2.6 million units during the quarter, with cumulative shipments of more than 3 million units since the smartphone’s launch in late November 2008.[9] Q2 results released July 16, 2009 reports 3.7 million units shipped during the quarter and more than 6.8 million units total have shipped since the release.
