I guess I'm less worried about the cost than I am about the functionality. I think adding this to the phone is pretty cheap since the speaker and microphone are already there. It would be nice to not get fingerprints on the display anymore, but I could see issues with accidental gestures. Just moving the phone to your ear could cause a recognized gesture. I also wonder how far away this would work. For a TV, it would have to work at 10 to 20 feet away to be useful. This could be very difficult to use for people who talk with their hands. But, I guess it's like all new technologies. We have to get used to it.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
