With the version of Adobe for the Playbook it needs to have a little more functionality. In the freeware version of Adobe Reader if you have a document that has a hyperlinked table of contents you can at least jump to pages. An index for the application would also be nice as well as the Search function.
It needs a lot more as well, bookmarking or as in the desktop version, recording what page I'm on when closing a pdf, fitting text to page when in portrait mode and not page dimensions, highlighting would be nice and note making. At the moment it's just a viewer for a single page or 2, reading a pdf book on it is unpleasant.
I was so looking forward to reading my pdf's on my playbook when it arrived, and so disappointed by the hurried cut down version.
