It's no surprise that technology companies such as Apple are considering the future of unified environments. For example, it's possible to control iTunes on your computer or your Apple TV with your iDevice and the Remote App. There are also Apps that turn your iPad into a second screen, or your iPhone into a trackpad over wifi. They aren't quite as fast as we'd like them to be yet, but it's a start.
The illustration above seems to show windows within the Mac OS that have various appliances around the home that can be controlled via computer. We don't mind the idea of turning on the dishwasher or the oven with a few taps and a slide…so long as Apple doesn't get into the business of making large household appliances. iWash and iDry, anyone?
