Should We Ban Hand-Held Devices for Kids?

Cris Rowan has a provocative but compelling piece in Huffington Post arguing that no one under 12 should use smart phones, tablets, or other devices.  Her reasons include studies linking the amount of screen time to radiation exposure, obesity, and attachment and developmental disorders.  Of course, a lot of this applies equally to adults, who should be careful about overexposure and especially the example they set in the use of their own devices.
