You know, I find that interesting. I don't believe that buying a physical book or movie gives me eternal license to the contents therein. I'm finally getting rid of my US house as my wife's moving over here to Poland, and I figure that any book or movie that I don't care enough to rebuy in digital editions is something that I don't care enough to own any more. I'm selling about ~2000 books and movies before moving, but since I haven't exactly had them handy to read over the last two and a half years, I won't miss them all that much.

Software, on the other hand, is something that I explicitly license and not own and I have no issue making endless digital backup copies of to reuse for as long as I may live, no matter where I go.

That seems really hard to do; scanning in an entire book is a heck of a pain in the bum. I will be a sad panda if that ever happens, though, because I just donated 2000 books to charity last weekend. :P
