If you're curious about home automation, or if you want to get a peek at INSTEON devices in action, a visit to Smarthome's Video Vault will be worthwhile.
For a good overview and demo of remotely controlling your home, start with the INSTEON remote link showcase video.
For a peek at what its like to install and configure the INSTEON starter kit, watch the Plug-in Dimmer Starter Kit video. As a bonus, you'll also get a nice tip about how to tell when outlets in your home are on the same electrical phase.
At this writing, there are over a dozen videos available. And, in a very nice move, written transcripts are also provided to make referring back to details much easier. However, the videos are in the proprietary WMV format. Mac users can use the free Flip4Mac QuickTIme component to view them; Linux users will have to rely on the transcripts. Aside from this unfortunate restriction, the Video Vault is a great resource.
