The N-Gage (a pun on engage ) is a smartphone and handheld game system from Nokia , announced on 4 November 2002 and released on 7 October 2003.  It runs the original Series 60 platform on Symbian OS v6.1. Its original development codename was Starship . [ citation needed ]
N-Gage attempted to lure gamers away from the Game Boy Advance by including mobile phone functionality. This was unsuccessful, partly because the buttons, designed for a phone, were not well-suited for gaming and when used as a phone 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 November 2005, 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.
