There is no "i" in team. There is one in your new Nintendo handheld. (There's two in "Wii", but I digress.) GoNintendo asked Ninty straight up what's with the I, and got an answer.
Nintendo insists it's not-follow-the-leader of Apple branding "i" on any must-haveable small gadget that exudes 2.0 coolness. Rather:
• The "i" is symbolic of the subject "I" and its personal aspect.
• Plus, the addition of two cameras gives the system its own "eye" on things.
"Nintendo hope that the Nintendo DSi becomes more than a game system and more of a personal tool to enrich our daily lives."
GoNintendo says that comes directly from a Nintendo rep.
