I guess it depends on what you do with the iPad. Currently, we use this as solely a web surfing device. We have no movies, pictures, music on it. I use my iPod for music. We don't play games with it. I assume in the future, we'll use the iPad for movies and maybe pictures, but we'll see. I have a 3TB drive with all my movies, pictures, music, home videos on it; we just bring my wife's laptop and watch everything using it. For us, the 16GB is plenty of space right now.
