Welcome to the world of iPhone! It just works. So fluid and easy. Very much a "no muss, no fuss" type device. I've never had an Andoid device, but I haven't heard good things. I came from BlackBerry and am so glad I'm back on iPhone.
Coming from a Original Droid, then a Droid X and finally a Droid Incredible to now a 4S. Gotta say, best decision ever. I absolutely love my iPhone! Hands down the best phone I've ever owned!
