"The great irony of these debates is that most new devices become popular only because buyers really want them, which means they open whole new markets that can then be monetized by rightsholders."
This, for me, is the crux of the article, and of the whole DRM/ebook piracy/death of pbook crisis - consumers WANT to buy the devices and WANT to buy the ebooks - they WANT to spend money. Book publishers are blindly following in the footsteps of the fools in this article and curtailing their own markets. Can anyone imagine the sales figures if Amazon supported ALL digital formats and provided downloaded copies to ANY device in ANY format? They could even keep some form of DRM on these copies - just offer all formats to anyone with a credit card.
Buy a new device? Simple, just get a new copy from Amazon. Not rocket science!
