I do have the problem many have experienced where sideloaded books are not sorted in any obvious way in the 'my documents' folder on the device. I am able to load epubs purchased from non-B&N sources, including Sony, without trouble. It’s a lot like the Kobo in that there’s a hardware Nook device and a companion app for Windows, Android, and iOS. Its Nook app is also a top solution to read ebooks. I've been using my nook successfully with my mac since I received it in december. Nook App (Windows, Android, iOS) Barnes & Noble are obviously a major player when it comes to physical books. You will, however, have to successfully authorize your nook with ADE before DRMed epubs will be accessible on it, regardless of how you later transfer content. I have also downloaded books within ADE on my mac and then transferred to 'my documents' directly on the nook, without using ADE to transfer.

One issue, however, is that the latest version of the nook firmware can cause the nook to not recognize the ADE folder, you need to manually drag ADE books out of the ADE folder on the nook and plop them into the 'my documents' folder. Books I have purchased which need to be downloaded through ADE also transfer to the nook without incident, ADE automatically recognized the device and authorized it. I'm not aware of any way to connect to it via wifi. I have had success loading DRMed epubs from sony directly to the device via USB.
