What's your greatest achievement? Satoru Iwata rescued Nintendo from its N64+GameCube lethargy (commercial success-wise; only a fool would deny the quality of many of those games) and turned it into a ridiculous success with the Wii and DS, so he's not sweating it either. That's why I'm loathe to criticize the man when he defends the Wii Vitality Sensor.
Says Nintendo's CEO:
When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking.
Remember the day when Nintendo revealed the Wii's name? How many people online were snickering, "lol name fail"? A lot! A couple months later, everyone on Planet Earth has Wii, and we're all playing Wii Sports.
Does the Wii Vitality Sensor sound silly today? Sure, I guess, but don't be surprised when, two years hence, we're all addicted to checking our vital signs.
