Yes, particularly in that you can annotate PDFs and those annotations will show up as a "table of contents" on the LCD side. The large screen makes most PDFs readible without much zooming, and depending on a given PDF, the PDF reflow mode allows you to read the contents even more comfortably. The one thing the eDGe doesn't yet do is allow you to read PDFs in landscape.

Alternatively, you can also read PDFs in portrait or landscape, in full colour, on the LCD side using the included PDF-to-Go application, although it doesn't allow annotation.
