Isn't it possible that, for everyone but the two participants (in the eink research) who were accustomed to reading on eink devices, the "check me out, I'm actually reading on a wizzbang gizmo!" factor might have skewed results? I know it wasn't a seamless transition from paper to electronic for myself. It took a while for the device to "go away." Doesn't make sense to me to try and form any permanent conclusions on retention/comprehension from a test where forty-eight of the fifty participants were still in the process of acclimating to the concept.
