Hi! I'm interested to get the Dataviz Document To Go Premium version. Anyone used it before and any comments?
-Is it good?
-Any issues/limitations?

By the way, I tried to search online for the pricing information.

Direct premium version = US$29.99
Viewer only version = US$9.99*
*upgrade available...but does anyone know the pricing information for upgrading from viewer version to premium version?

Thanks!
