This question has some bearing on another thread about rooting and security. Let's say someone had several Barnes an Noble books that they had stripped the DRM from, and they had placed these books in the "myDocouments" folder in Nook. The purpose of stripping the DRM had been to be able to view the files in other e readers and manage and read them with calibre on his computer, not piracy Anyway, just suppose one day, as this person shut down Nook to do something else, a message came on the screen that several files were being erased. Later he looked and the myDocuments directory was empty Is it reasonable to assume that this would be a willful action by B&N? Would rooting the machine have prevented this? If not preventing it just by rooting, could it help prevent it by changing permissions on the myDocuments folder? I do know that Barnes an Noble will enter your machine after a purchase. My first purchase was accidentally made with an invalid card. The purchase went through. I could open the file. Then, a few hours later, the file would not open. I called Barnes and Noble, and they informed me that I had used an old, invalid card, and we were able to fix the situation. But the fact is, they were able to poke around inside my machine and change things. I know that there are probably lots of people poking around inside my phone and my computer, but I really don't like it.
