From our "What Will They Think of Next" file, comes an oven that refrigerates as well as cooks. Or is it a refrigerator that cools as well as cooks? Either way, here's how the Connect IO refrigerated wall oven from TMIO works: Before you leave for work in the morning, you simply pop a dinner entrée into the oven. The oven, er, refrigerator, keeps the food cold all day long. Just before you leave work, you can turn on the oven from any computer or cell phone with an Internet connection. By the time you get home, your meal is waiting, although you have to serve yourself. The Connect IO costs about $5,800.
