Microsoft and the Industrial Designers Society of America (IDSA) are in the middle of the Next-Gen PC Design Competition, and one of the entries is Yummy Kitchen Connect, a design concept for a wall-mounted touchscreen PC that keeps track of food you have in the house using a barcode scanner on the bottom that's connected to a community database.
You tell the device your diet and your favorite recipes, and it hooks up to the blogosphere to help recommend what might like for dinner according to your likes and dislikes. Since it keeps track of what food you have your pantry, it can also recommend a shopping list. Once you have all your ingredients together, it can show you recipes and tutorials right there in the kitchen while you're preparing your meals.
