The N-Gage is a smartphone and handheld game system from Nokia that attempted to lure gamers away from the Game Boy Advance by including phone functionality. This was unsuccessful, partly because the buttons were not well-suited for gaming and because when used as a phone it was described as resembling a taco. It was released on October 7th 2003 for $299.00, which would equate to $404.94 today.

The N-Gage QD was a smaller re-release that fixed the problematic cartridge placement and repositioned the microphone. It removed several features including MP3 playback, FM radio reception and USB connectivity.
