Now HERE is a nifty use of existing technologies. They aren’t quite up and running yet, but when they are (depending on the cost, of course), I am all over the Lifestyle Scanner!

It’s a keyring barcode scanner. You scan everything you eat and their website compares it to the nutritional goals you’ve set (based on your particular diet). They even have a database of foods for the things you can’t scan.

Now, I wonder what it will cost…
