When it comes to faithfully viewing and rendering a Microsoft Office or iWork document on your iPhone or iPod Touch, Documents To Go quickly proves its competence by delivering crisp, clear reproductions of your Word, PowerPoint, PDF, and Excel documents, and even Microsoft Office 2007 files. Most core tools to create, edit, save, and send Microsoft Word and Excel documents are tucked within expanding tool menus. Tools include Apple's copy/paste, font and paragraph style, and lists, among others. Many are intuitive, but some require some trial and error before you become familiar with which icons do what.
Advanced business professionals using this "Exchange" version pay a premium to view attachments sent through the Microsoft Exchange Server. The app essentially asks you to set up a Microsoft Exchange account to view the supported attachments, even if you've already done so in the iPhone in-box. Setup is a hassle, especially for those unfamiliar with their Exchange server information. After setup, however, viewing e-mail attachments from the Docs To Go in-box is a bit laggy, but otherwise competent.
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.
While the desktop companion helps make the app more useful, its Wi-Fi requirement puts a crimp in its usability. However, those who work predominantly with Word and Excel applications and have ample wireless networks at their disposal will find Documents To Go a welcome part of the productivity toolbox.
