Excellent document. While a little biased, SmartLabs is doing excellent consumer education not only about their own technology, but also about all other technologies available.
Competitors (UPB, Z-Wave, Zigbee) should be worried that the most comprehensive information that the consumers are getting about their own products come from SmartLabs. These papers certainly influence our purchasing decisions. And we influence a lot of people (customers, friends, etc). They should re-think the business models.
On the other hand, SmartLabs just need to stop bluffing about the dual band and start releasing some value added RF devices (at least some Insteon compatible palmpads-like device). A phase coupler is just a given in any technology - does not add value at all.
