Documents To Go Premium for iPhone, iPad for iOS

Documents To Go quickly proves its competence by delivering crisp, clear reproductions of your Word, PowerPoint, PDF, Excel, and iWork documents, including Microsoft Office 2007 files. Most core tools to create, edit, save, and send Microsoft Word, Excel documents, and PowerPoint presentations are tucked into expanding tool menus. Although much of the app's navigation is intuitive, expect some trial and error. The newest tool, for editing and creating PowerPoint presentations, is the most limited in what it can do.

Opening e-mail attachments sent through Microsoft Exchange or through Gmail (but not both) is a boon for many users, who must nevertheless set up a syncing account to view the supported attachments from the app interface itself, instead of from the iPhone in-box. Setup is a hassle, especially for those unfamiliar with their Exchange server information. Viewing e-mail attachments from the Docs To Go in-box after setup can be a bit laggy, but is otherwise complete.

In addition to the iPhone app, Documents To Go gives you the option of downloading a free companion desktop application that syncs files and folders between your iPhone and Windows or Mac computer. You can also drag items into a desktop folder for a quick sync. Syncing worked well, but the setup was a little laborious, and the Wi-Fi requirement to initiate a sync shuts out home and corporate users who get their Internet from an Ethernet cable.

Though the desktop companion helps make the app more useful, its Wi-Fi requirement puts a crimp in usability. However, those who work predominantly with Microsoft Office applications and have ample wireless networks at their disposal will find Documents To Go a welcome part of the productivity toolbox.
