Wifi Bathroom Scales
One of the sure fire hits of 2010 is the Wifi Bathroom Scale. This ingenious product records and sends your weight to your own (password protected) WiThings account. From there you can track how your weight rises and falls over time, as well as other metrics such as BMI. You can also access the data on your iPhone as well as linking it to other weight loss iPhone apps. The only issue we can see is the price tag (over £100).
