Rejoice, Microsoft Office and iPhone users, because now you can edit, create, and view Microsoft Word documents. Dataviz Documents To Go doesn't bring Excel editing, but at least is now here for $US5. And there's more.
The Excel creation and editing will be a free upgrade if you buy now. Like the rest of the Dataviz mobile editors, Documents to Go for iPhone uses InTact, which retains the format of edited files at all times.
