The Nokia N900 is a smartphone made by Nokia. It supersedes the Nokia N810. Its default operating system, Maemo 5, is a Linux-based OS originally developed for the Nokia 770 Internet Tablet. It is the first Nokia device based upon the Texas Instruments OMAP3 microprocessor with the ARM Cortex-A8 core. Unlike the three Nokia Internet tablets preceding it, the Nokia N900 is the first Maemo device to include phone functionality (quad-band GSM and 3G UMTS/HSDPA). The N900 functions as a mobile Internet device, and includes e-mail, web browsing and access to online services, a 5-megapixel digital camera for still or video photography, a portable media player for music and video, calculator, games console and word processor, SMS, as well as mobile telephony using either a mobile network or VoIP via Internet (mobile or Wi-Fi).〔(Response from Nokia support to customer enquiry )〕 Maemo provides an X-terminal interface for interacting with the core operating system. It was launched at Nokia World on 2 September 2009 and was released on 11 November 2009 in the United States and 9 European countries. The N900 was launched alongside Maemo 5, giving the device an overall more touch-friendly interface than its predecessors and a customizable home screen which mixes application icons with shortcuts and widgets. Maemo 5 supports Adobe Flash Player 9.4, and includes many applications designed specifically for the mobile platform such as a new touch-friendly media player.〔(【引用サイトリンク】date=27 August 2010 )〕 == History and availability == The Nokia N900 was announced on 17 September 2008 during a keynote presentation by Dr. Ari Jaaksi of Nokia.
