The funny thing is...
People talk about the DRM meaning they are licensing, not owning. What if the computer croaks, and they lose the work? They have to buy it again (or maybe there is a limit to the number of downloads, so you can replace it a few times). Guess what happens if a fire tore through your house today, destroying all your books, CDs, DVDs, computer, and other material goods? It's gone! You can't go back to a website and re-download everything. You have to buy it all again.
*GASP!*
Just deal with the fact that we don't actually own anything, material or digital. We are renting it until it gives up the ghost. That might be 1 year, it might be 99. It might last 100 generations. But there is no guarantee that you will have it for more than 10 minutes after you buy it. Yes, there are warranties, but they generally cover the workmanship, not the realities of life such as fire, flood, storm, theft, etc. Yes, we have insurance, but as most people will tell you, it's good for rebuilding what was lost, if within the confines of the policy. It's not as if it was free, because of the premium you pay, and there might be depreciation factored in, meaning you only get 70% of the replacement value.
So, realize people that just because it's digital, and it's 0s and 1s instead of a book on your shelf, that it doesn't make it any better or more secure. Can we argue about pricing? Hell yes, but that's completely different, and that is set by free markets... which in this case are not well set, because it's still rather new. And we don't know what the production costs are, but I have a sneaking suspicion that it's a heck of a lot more expensive to transcribe, edit, and transform something written 90 years ago to a digital format than to move the latest crap-pop record to mp3, FLAC, or other format.
In other words, realize that nothing is free or owned, and the best you can hope for is to take care of it. And if it burns, well, you're out of luck.
