"is worth it" requires people to be fully aware of what's going on.
I've described what some of these devices are doing based on product announcements, patents, investigative news stories, and that sort of thing. I've had numerous people tell me that I'm wrong. That they don't believe companies are doing this.
This has caused me to come to the conclusion that people aren't aware of the trade-offs or what is going on.
That lack of understanding concerns me.
