4 months after our 2nd child was born my wife still wasn't getting enough sleep. Part of that was the child's sleeping pattern and part of it was her not being disciplined with sleep (not taking naps or staying up even later). Of course my telling her "you need more sleep" fell on deaf ears. So I recommended she get a fitbit since it claims to track one's sleep. It was a big reality check to see on her computer in a big red circle that she was only getting on average 4hrs of sleep each day. Just seeing it on the computer meant she could no longer ignore the truth. It's the same as a doctor's prognosis vs. a friends opinion. The former carries a lot more weight. She started getting more sleep the following week.

If someone can create a system that nearly automates the tracking of what you eat you'll make gazillions and help a lot of people along the way. Maybe a bluetooth food scale in conjunction with a tablet that can do "facial recognition" on a plate of food to estimate what I'm eating and the carb/protein/fat/calorie breakdown. Then based on my physical activity for the day and calorie consumption it could recommend I skip desert or have a carrot instead.
