The ability to load and read DRM-free books is a near-universal standard for ereaders and ereading apps for mobile devices. (Allowing DRM-locked free books such as library books is another thing entirely, and, to our minds, gives an advantage to certain devices.) Any reader that does not allow for free, unlocked content, such as the thousands of public domain books out there, is not worth anyone’s consideration as a viable ereading experience.

To say the ability to access DRM-free books is an advantage is akin to calling a car with a windshield advantaged. Sure, you could drive without one, but it would suck. Keeping up the car metaphors, Bookz is a Tin Lizzie.
