Addicted to your smartphone? Welcome to apple rehab [Spectral Lines]

We've all been there: You're out with friends for dinner and everyone has finished their entrees and placed orders for coffee and dessert. The conversation seems to fade along with the food and, almost simultaneously, everyone suddenly realizes they have to give their phones a quick peek- any text messages? And as long as it's in their hands, maybe a glance at email or Facebook. The scrolling goes on until the coffee arrives.
