Well, I decided to buy one. I have a MacBook Pro. I tried connecting my new Nook to my Mac. At first, Android File Transfer popped up like it should. I tried to transfer a file from my Mac to my Nook, but the Nook window in Android File Transfer wouldn't take it (very odd). Then, the next time I connected my Nook to my Mac, Android File Transfer didn't come up. When I started it up, it asked me to connect an Android device by USB cable. So, my Mac can't "see" my Nook at all now. I tried resetting my Nook and still no go. Any suggestions?

Edit: My Nook now is "seen" by my Mac. Not sure why! Android File Transfer can see it. I can transfer books that way, but I cannot create new folders on the Nook through Android File Transfer.

Then, I started playing with Calibre. I got the same "failure to communicate" message when I first connected my Nook to Calibre. However, after a little while, I used the "configure device" feature in Calibre to tell Calibre where to send books. Then I tried sending books. Calibre could not see the books on my Nook, and they didn't show up on my Nook. But then, a few minutes later, they showed up in my Nook library. The next book I sent showed up immediately in my Nook library. But Calibre can't see the books on my Nook. That's where the communication glitch seems to be.
