New York governor to launch bill banning smartphones in schools
(www.theguardian.com)
This is a most excellent place for technology news and articles.
I was trying to think how this could be enforced. It actually makes sense when you frame it this way, didn't think about the parent side. "Sorry Karen, that's the law! Your kid week get her phone back in a week!"
Most send it to the front office and the parent can pick it up after school.
