Here is a video for the Finale app for the iPad demonstrations by a representative from the company. The app is a viewer that will fully read and open Finale apps so users can use iPads as their new music binder.
Standard swiping features found on the iPad work here fully so navigation should be natural for iPad owners. It also features the animated pages turning found in the iBooks. The app supports multipule languages for those now in a English speaking country.
More features will be added as they approach their release window, in which they are looking at the Spring.
I know one Lazy Tech Guy is probably looking at this and is already finding a need for it.
