Nintendo DSi Popularity & Sales: 83M+ Units, Iteration of DS, Now Retro Favorite

83+ million units sold worldwide (2009–2014). Key points:

• Iteration of DS (154M) – added cameras, SD slot, larger screens, DSiWare shop.
• Strong holiday sales; multiple limited editions (Zelda, Mario, colors).
• Replaced by 3DS (2011) but coexisted for years.
• Today: Nostalgic collector item; DSiWare shop closed (2017); homebrew scene active (Memory Pit exploit).

It was a major success in its window, now a retro favorite.
