Yesterday Nintendo began selling the upgraded version of their popular DS handheld system, and by all accounts sales are going very well. 1up has a look at the story of the DS so far, from somewhat rocky launch up through this last amazing Christmas season. From the article: "Nintendo had lost its collective mind. At least, that's how it looked back in January 2004 when the company announced its latest system, the DS. 'We have developed Nintendo DS based upon a completely different concept from existing game devices in order to provide players with a unique entertainment experience for the 21st century,' company president Satoru Iwata stated--a bold proclamation. But few were buying it." PC Magazine has details on what was upgraded, and Engadget has pictures from the NYC launch party.
