I seem to keep falling in the middle of you guys
To me, the people that remove DRM (like myself, but a small minority of ebook buyers) are safe, ether way it goes. The ebooks in my collection will still work 20 years from now, as I can convert with ease to whatever "standard" may be set.
The people that leave DRM are screwed no matter what. Eventually the company they buy from will go out of business, change formats....whatever. So 20 years from now odds are they will be unable to read the books they "own" on the then current reading devices. But the Amazon buyers will be even more screwed than the ADE buyers. Amazon books are tied to Amazon readers (just as Amazon wants it). That consist of ONE hardware reader brand, and less than a half dozen software readers. ePubs are spread out with variable DRM schemes, but the format is there for virtually every current hardware and software.... except Amazon.
Anyway, the lesson to me is simple. Learn to strip DRM from your books, or realize you are just renting the book for a limited time.....
