Dropbox is a fantastic tool for storing, organizing, and sharing files. It is particularly useful when working with large, shared media files (i.e. photos, videos, audio). The Dropbox iPad app also seamlessly integrates with a number of other apps. For example, an instructor could record a screencast with a tool, such as Explain a Website, export that file to Dropbox, and then share the link to that file with students. An instructor could also choose to allow the Dropbox app to access their iPad photos. Those images would then automatically copy over to Dropbox. One word of caution: You will want to keep tabs on the amount of Dropbox storage space you are using. Pictures can quickly fill that space. You will also want to be cautious when working with files shared with you. Once files are deleted, there's not a way to get them back, at least not that I've found. But overall, this is a terrific app. It's clean interface is very user friendly.
