I don't know - with the research they've done over the past few decades about circadian rhythm, I can see a lot of benefit from lighting that responds in both intensity and color to time and or motion. Likewise with HVAC. But neither of these needs the outside 'net.
Where I really see benefit from external communication would be mostly Boolean data such as whether the kids made it home from school, is there a break in the dog's underground fence line, is moisture pooling where it's not supposed to, or whether the CO/smoke detector has alerted. For information that goes in instead of out, I could also see a benefit for automatic storm shuttering when NOAA issues a severe thunderstorm warning and an automatic disabling of the sprinkler system if the county passes a watering moratorium (i.e. save me from fines if I'm absentminded and forget about turning it off).
Where's a better place for a discussion which may introduce truth and actual intellectual debate? Maybe someone there will point out a real conservative viewpoint such as Augustine's from around AD 400 which by using the text of the Bible alone came up with the conclusion that a strictly (simplistic) literal interpretation was impossible and also never intended. Augustine also pointed out that some of the greatest damage that can be done to the Church is by scientifically-ignorant believers who attempt to lecture scientific experts about how the experts are wrong in their views.
Unfortunately for Christians, and just about every other group ever organized with a human membership component, ignorance at the adult stage is usually manifest in a self reinforcing mindset and not one welcome to instruction.
It seems as if an always on OLED display would be the major source of battery drain - and so I don't get why watch makers haven't used e-ink. Come into the market as Timex and not a Rolex. A simplistic device which displayed time and push notifications at a $50 price point seems like it'd quickly dominate the market. Heck, you could even make it an e-ink background to a nice analog watch for that matter (although that'd probably up the total price). This sort of thing wouldn't need the processing power (i.e. more battery drain) as the current giant glossy types either. Perhaps I'm being naive, but I don't get the high-end luxury approach.
Open API would be natural too; especially given a low price point this type of watch could quickly be a community favorite.
