Documents To Go Premium, the office-suite software from DataViz, has been updated to support iPad.

These were the first updates of the application following Blackberry-maker RIM's partial acquisition of Documents To Go creators DataViz.

We can assume that 4.0 was mostly in the can when RIM bought DataViz's assets early this month.

Now that RIM has bought the better chunk of DataViz to work for Blackberry, its days as a cross-platform mobile superstar might be numbered.

By buying Documents To Go and its software team from DataViz, RIM just solidified its position as the "serious" and "productive" smartphone company.
