Re: I don't get it
"I also think smart watches would be a welcome for parents who want to keep tabs on their children (like where they go etc), and this new field of security for children would be a deciding factor in pushing the sales of smart watches."
I am not sure I understand your idea about smartwatches becoming a tool for imprisoning children. It sounds like a really bad idea if you want to teach trust to your kids by letting them know you don't trust them.
The best way to know where you kids go, do, etc. is by teaching trust to them, by having an open dialogue and a good, honest communication. Kids are not born knowing everything. They need to be taught things about life, dangers, and all.
That idea would be just the wrong marketing strategy for anything.
