$99 fitbit Tells You a Lot More Than a Pedometer

I’ve always been interested in gizmos that can tell me things about what I and other people are doing. I went through a bunch of bicycle computers back in the days when I practically lived on one (didn’t have a car for a stretch). And, of course, I went through a bunch of pedometers (none of them really seemed to measure things correctly). My favorite feature in the new 5th generation iPod nano is its pedometer (no, really!).
