This year finally the kids are getting ebook readers for Christmas. So far I have been holding off from purchasing such devices because of the Digital Restrictions Management which is associated with them.
My opposition to them changed somewhat when I found that one of my favorite book publishers (O'Reilly) does not use any DRM and they actually trust their customers enough to take their word for it when they state that they already own the paper copy of a book so that they can then qualify for a $5 upgrade to the digital version. And these are not cheap books often between $50 and $100 per copy. This has bought a lot of good will from me, and when I am looking for technical books in the future (which I do frequently) I will certainly try to give preference to O'Reilly.
