Not true in the context of buying a book reader (Which is what I believe we were talking about in this thread, were we not?)
This is ONLY true when trying to buy books from B&N, NOT when buying their eReader Nook models.
In other words, if you have a Nook you bought from B&N, you can use it to read DRM protected books from literally FIVE different major online bookstores without running into any DRM problems (B&N, Kobo, Borders, Sony, and Google)
Currently, I believe that it's still true that if you use B&N's PC or Android App to purchase and download a book, though you can read it on that device using the B&N App, you CAN'T then move it to your Sony, Kobo, Aluratek Libre, Jetbook, or other Adobe Adept EPUB device.
This is a really, really, really, STUPID thing for B&N to have done, because it means that though they are giving up potentially MILLIONS in sales to other bookstores by letting Nook owners buy from them, they are NOT in a position to perhaps also reap MILLIONS of dollars in sales from users of reader devices sold by those other bookstores in return.
In other words, by posting a lower price on a specific title (or by having a special promotion) Kobo can steal a book sale from B&N, by selling to one of B&N's Nook owners, but no matter how good the promotional deal is at B&N, a Kobo reader owner can't buy from B&N unless they want to deal with removing the DRM somehow, just to save a dollar or two (and most don't).
THIS IS FLAT OUT STUPID. Giving up sales to your competitors willingly, but NEVER being in the position to make them return the favor?
DUMB - REALLY, REALLY, DUMB.
If Liberty or some other bidder does buy B&N, they should fix this instantly, and FIRE THE B&N CEO (after all those MILLIONS in lost sales that B&N has walked away from, through this foolishness are, of course, estimated and deducted from his fatcat 'golden parachute')
Someone PLEASE correct me if this has been fixed, but so far as I know, though B&N has been 'talking' about fixing the incompatibilities between B&N and Adobe DRM for many, many months,
THIS IS STILL AN ISSUE.
