My first reaction was to scoff, but this actually improves e-readers in a few critical ways. E-ink screens have been so easy to break that they all but require a (usually) cumbersome case to survive a trip in a backpack or, say, accidentally rolling over on it in bed. This should improve that, and it sounds like the weight savings aren't negligible either. Amazing that we're close to being able to carry a library in something barely heavier than a sheet of paper. This will also make larger format readers more practical.
