One thing I wonder about some types of software is “what happens when RIM bundles it with the device?” This was certainly the case with Documents To Go, which will be integrating full document viewing and editing with OS 4.5. Well, DataViz just put up the features of their Premium Edition. So what does the premium version have that the standard doesn’t? For one, document creation (the standard edition only lets you edit existing docs). For two, fancy text formatting like font size changes, bullets and paragraphs are only on the premium version. It’s a pretty slick strategy there – get their basic software on every BlackBerry out there, then when users get frustrated that they can’t do what they want to do, they’re roped into the premium service. Very sly. You’ll be looking at $69.99 for the full premium version of Documents To Go.
