I have an Iphone and it is a lot like having your computer and GPS everywhere you go. It will tell you about the weather. It lets me do my banking. I can load a ton of music. I can send and receicve pictures. I can even locate my wife or at least her phone by GPS. I don't even need to bring a book to the doctor office, I have kindle loaded and can retrieve my books. It has built in Navagation so if you ever get off track on a long ride just turn on the phone it will show me where I am and how to get where I want to go.
Sometimes I think the phone is smarter than me.
