Samsung shows home automation using Android Galaxy Tab

Samsung didn't show off this functionality during its North American demo.
Another great use of the Galaxy Tab, which Samsung is positioning as a "take with you tablet," is as a home automation device. Here's a presentation (via Engadget) http://www.engadget.com/2010/09/27/samsung-galaxy-tab-as-home-watcher-remote-control-video/of the Galaxy Tab being used to control various devices around the house:

The demo depicts live widget-based control over your home's HVAC, TV (including remote viewing), stove, oven, dryer, vacuum robot, and refrigerator with integrated grocery manager that suggests recipes based upon the food you have.

 Look for Verizon (VZ) to sign exclusive contracts with refrigerator/stove makers so that other carriers' Android devices can't communicate with them.
