Apple touted iBooks 1.1 as a major upgrade which allows users to sync and view PDFs from their computer to the iPad. While Apple has delivered the ability to sync and view PDFs in iBooks 1.1, there are some major limitations, including some features that iBooks 1.1 is advertised as being able to do, but actually cannot. The image above is a screen shot from Apple's iBooks page. It states:
The problems with this is that you can't actually flip through pages or add highlights to a PDF. There's a difference between flipping through pages and swiping. iBooks 1.1 lets you swipe one page off the screen in order to bring on the next. That's very different than flipping the page as you do with an ebook in iBooks. As for highlighting – well, the feature just isn't there.Tap a PDF to read it and it fills the screen just like an ebook. You can flip through pages, add bookmarks and highlights, or zoom in for a closer look.
