Training & Nutrition - Food trackers, this is cool, but is it worth it?

I'm a gadget person and found this:

Apparently you scan the UPC code on packages of food (it even knows a lot of restaurant foods) and the nutritional data is then tracked for you.

The website with more explanation of what this can do is here: http://www.trainingpeaks.com/caloriescanner/

Is this a valuable tool or just a gadget thingie that doesn't have practical use? I suppose it's like a cool electronic diary, but what can I use it for other than easily logging what I eat?

It looks neat but I think I need an angel (or demon?) on my shoulder telling me if it's a waste of money (it's $150) or not.

Thanks.

$150 gets you the tracker and a month subscription. Depending on the plan you choose, you could end up spending over $200. Since it reads UPC codes, you're out of luck when you go out to eat. Unless you need to micromanage your food intake, it sounds like a cool gadget but not necessarily useful.

I guess I needed someone else to tell me the same thing. Thank for saving me $$! Now... maybe I can buy a new jersey instead? ;)
