I'm going to travel with my iPhone for the first time this holiday. In the past I would need so many devices to keep me entertained. With the iPhone you no longer need your laptop plus DVD player us cell. I will download movies and shows from iTunes. I can email my PDF homework to myself to read. Laptop? Nope, unless you have heavy computing to do. You can surf the web on the iPhone. I am so excited and anxious to travel lighter with this device.
