The N-Gage is a smartphone combining features of a mobile phone and a handheld game system developed by Nokia, announced on 4 November 2002 and released on 7 October 2003.[2] It runs the original Series 60 platform on Symbian OS v6.1. N-Gage attempted to lure gamers away from the Game Boy Advance by including telephone functionality. This was unsuccessful, partly because the buttons, designed for a telephone, were not well-suited for gaming. The original N-Gage was described as resembling a taco, which led to its mocking nickname "taco phone". Nokia introduced the N-Gage QD in 2004 as a redesign of the original "Classic" N-Gage, fixing widely criticized issues and design problems. However, the new model was unable to make an impact, and with only 2 million units sold in its two years, the N-Gage and its QD model were a commercial failure, unable to challenge their Nintendo rival. The N-Gage was discontinued in February 2006, with Nokia moving its gaming capabilities onto selected Series 60 smartphones. This was announced as the N-Gage platform or "N-Gage 2.0" in 2007, carrying on the N-Gage name.
