How many times a day do you check email, twitter, facebook, etc? Is the iphone the last thing you look at at night before you sleep and the first thing you check in the morning? Do you feel anxious when you leave it at home? I am begining to think that the iphone facilitates a connectivity disorder/addiction. Since people can be addicted to gambling, clearly you do not need a substance that causes addiction. What do you guys think? Is this addiction or are our phones meerly aids like a wristwatch that make us more effective?
