If you did leave the oven on, an Android device probably won't help. But there are apps out there that will help you manage other aspects of house and home while at the office or on the road. You can manage your DVR, adjust your Wi-Fi-enabled thermostat, and keep tabs on your home security system, for example. Actually, there is such a thing as a Wi-Fi oven you can control with an Android phone -- the Samsung product just isn't widely available yet. Alas, developers haven't figured out an app that can walk your dog.
