I was surfing the internet with the hidden browser and googled some video to check youtube in nook touch. I clicked on one result that took me to a youtube page saying the video couldn't be streamed. That page changed the orientation of the screen to landscape which remained unchanged while browsing and reading the current book. After clicking HOME it all came back to portrait.
I think the browser has a context menu that lets you switch orientation. But that has no relevance to PDF or ePub viewer.
As far as PDF is concerned, unless it is 'locked' or DRMed, you can rotate the pages using a PDF authoring tool so they display as desired on Nook Touch.
