One thing worth considering is that lock-in may not be such a big deal for many people when it comes to books. Most music, you may listen to many times over a range of years. On the other hand, there are plenty books you'll only read once (for instance, I'm reading about 100 books for a degree I'm working on, and most I'll never touch again). So, portability will not be such a big issue for many purchases.
