I have a Nook. Can I download all ebooks listed as compatible for a PC or just the ones specified as Adobe or PDF?
With your Nook you will be able to download Adobe PDF ebooks. If you are working from a PC, choose the items with the highlighted PC box. If you are working from a Mac, choose the items with the Mac option highlighted.
