The Nokia N-Gage dared to merge cellphone and handheld gaming, yet it never fully realized its potential. Looking back, what peripheral or accessory could have pushed it over the edge? A landscape-mode clip-on controller, a swappable cartridge grip, Bluetooth headset integration for seamless voice chat - what hardware add-on would have elevated its versatility? How might such an accessory have improved ergonomics, multiplayer connectivity or multimedia functions? And could modular attachments have set a precedent for today’s mobile gaming markets?

A physical keyboard, or at least a more responsive touchscreen, would have dramatically improved the N-Gage's versatility.  Typing, navigation, and more complex controls would have opened up a wider range of games and applications.
