USA Today has a good piece up today about the coming ubiquity of motion sensing accelerometers in consumer gear.

A lot of the focus (as is the case in many similar articles) is on the iPhone (and iPod Touch) — a large number of the apps being launched in the iTunes App Store are using the accelerometer, and it’s no longer just games.

An interested startup (new to us) mentioned in the article was Fitbit. Fitbit’s $99 motion sensor is designed to track a user’s motion throughout the day (and night) to track exercise, calories burned and even how well some sleeps. Pretty cool stuff and something we’ll be digging into in the near future.
