B&N have updated their Nook app. The new version 2.5 doesn't really add much:
- A new library ‘grid view’ to see more of your book covers on one screen
- A progress meter when downloading books
- A new menu option in the shop to view or add books to your wish list
But on the upside, there are reports that B&N plan to release a version for honeycomb sometime this Spring; that one should work a lot better on large tablets.
