How could Adobe even contemplate releasing a piece of book reading software that doesn't allow you to rotate pages. Is Adobe aware of landscape format? If I pay $30 for a book, I want to be able to read the pages the right way up! I will never, ever use DE again.
We regret that we cannot support all features in our initial release. Our team is small and working very hard. We do see the value of the feature, we just couldn't get it into our 1.0 release. Reader 7.0.9 is still available and does support that feature.
