When I first learned about Apple’s FaceTime video-calling feature on its iPhone 4 units, I was a bit skeptical. I thought there were too many hoops to jump through. I thought Apple’s TV ad with families gushing over newborn babies and showing off ultrasounds to soldiers was just a sappy marketing ploy. And the free 888 FaceTime number Apple created to let customers FaceTime with some stranger employed by Apple? I never bothered to try it out. After using it, though, I realize I was wrong. Now, one thing is certain: Apple’s FaceTime video calling simply rocks.
