Ooooo, I hadn't even thought about the implications of a roll-up
battery on portable electronics! They could be ... significant. When the battery is just a layer (or layers) between other components in the case, things could get very interesting.
As for putting the battery in front of the screen, yvanleterrible, I meant that tongue-in-cheek as an attempt at an eye-catching headline, not necessarily as a literal suggestion. Although if an application came along where it made sense to do it (and I agree that e-ink isn't one, not at the moment, anyway), then more power to 'em. Until then, I think the battery can stay safely out of site, even if did happen to be transparent.
