We heard at first that RIM did acquire DataViz and their Documents To Go product but that does not seem to be the case according to a statement DataViz gave BrightHand:
It is not our practice to disclose details of our business relationships with our partners. That being said, while we did sell some of our assets to RIM, DataViz itself has not been acquired and is still very much in business.
We remain committed to many of the platforms that we supported previously including both iPhone and Android. In fact, we will be releasing several new versions of Documents To Go in the coming weeks and you can expect to see other offerings from us in the future as well.
It looks like RIM must have only purchased the BlackBerry version of Documents to Go or the licenses to it… On the other hand it has always blown my mind that the premium version for BlackBerry costs $19.99 when the iPhone version costs $16.99 and seems to have more features. On the other hand the iPhone does not come with a free viewing version preloaded (it costs $9.99) which may be the reason for the difference.
Hopefully RIM purchased the assets so they can offer the premium version free…
