During his WWDC 2010 keynote, Steve Jobs announced some upcoming enhancements to the iBooks app. The biggest, by our estimation, is the addition of native PDF support. You’ll be able to drag PDFs into iTunes to have them sync up with iBooks. In order to keep things nice and tidy, PDFs will even have their own bookshelf. Other enhancements include one-touch bookmarking of a page, as well as the ability to add notes. The notes appear as post-it notes on a page. These are in addition to the currently available highlighting. Very nice.
