HBR w/o DRM

Mary sez, "Following the lead of Baen, O'Reilly Media, and Tor, the Harvard Business Review has decided to go DRM free." They say, "We make our ebooks available to you DRM-free so you can read them on the device of your choice. We trust that our customers will abide by copyright law and refrain from distributing ebook files illegally. Please note that in the case that you download a PDF, it will be personalized with your email address."
