I've been using a similar device for a year now - the Wattson Home Energy Meter (http://www.diykyoto.com http://www.diykyoto.com). It's not as full featured as Wattvision and doesn't connect over WiFi, but the information it reveals is extremely interesting and enlightening. It's easy to merely understand power usage (I always have done), but to see it revealed and presented like this is particularly fascinating. It's makes you stop and think. This is a good thing, for both environmental and educational reasons. I can't wait to get my hands on Wattvision, and good luck to them!
