It's rarely how the system is planned to work that's the problem: it's the failure handling, and other unforeseen events. The buyer usually has to take these things entirely on trust ... and when that trust turns out to have been misplaced, the reaction sets in. How long will it take to know what those failures are?
Here is a wild guess about a possible failure ...
Licensed books are, perhaps, tied to the device by some kind of device identity. If that identity data should go away for any reason -- say, total battery failure, or some form of short-circuit (spilled coffee?) and the consequent failure of the identity storage -- existing purchases will also go away.
(Of course, if the purchases are tied to a person rather than a device, other possibilities for failure open up, as well.)
Similar problems exist with any DRM solution, and I'm sure many already have experienced them personally. Still, I think any DRM solution needs to be evaluated from the perspective of how it fails and recovers, as well as from how failure-free operation performs.
