Hitachi has developed a Biometric Wristwatch. While working 24 hours a day for 10 consecutive days, it will analyze your pulse, your sleeping habits, and your exercise routine. Based on a prototype they developed two years ago, the watch now has a lighter weight of 40 grams and is half the size at 43 x 35 x 15 mm. You only need to connect to your PC (wirelessly) to read the data. We think that we are already nervous about a device that tells us that we eat too much and exercise too little. Expect it to hit the market in 2008.
