Did you know a smartphone can be a flashlight? It's true! The App store has several flashlight apps for free. I believe they are all pretty much the same. The idea is to get the app and when you need a flashlight you have one ready.
BTW I've had this app a long time but we were talking about great apps at Christmas and "flashlight" was mentioned ... And we all had stories about how useful it was.
Regarding smartphones--I was in a long line the other day and everyone in the line was playing with his or her smartphone. They were reading email or texting or playing games. No one was bored and everyone in the line was calmly waiting for his or her number to be called. I don't know what that means, but it was interesting to see. Smartphone as adult pacifier?
