One small piece of this has reignited my desire to build something similar to the BERG Tiny Printer [1]. My only issue with such a thing is that I don't want to use thermal paper.. or any paper if I can avoid it.
Going forward, I think there may be a market for a small eink tablet (~4.5" or so) that presents curated news, articles, etc -- something ideal for commuting by bus, plane, or any other passive time without loads of animated ads, popups for newsletters, and absolutely nothing 'social.' This leads me toward a desire for proper epub releases for magazines like The New Yorker and stuff that could scale to a smaller screen.
Services like Zinio [2], which most libraries provide, would be an excellent tie-in for a small device like this.
