I did the "little plop" - 9.99 - and am really enjoying the nutrition software. I find it very easy to use and I like seeing the ratings of how well I am eating - very motivating for me. Once they get all the bugs out and have the ipod downloads available I will probably get the 1-year $100 package.
The one thing that I think would be a nice addition, that isn't there now, would be the ability to link up the meal planner/tracker with my workouts. It would be very cool if the meal planner could adjust my calorie/carbohydrate/protein/fat needs based on the workout I did. But it is still fine the way it is now. It does take your general activity level into consideration when determining what nutrients and calories you need.
