Slow refresh rate of e-ink (1.35 Hz), limited contrast and shade resolution, no touch screen yet and a book-centric context make the immediate scope of apps a lot less varied than say the iPad. Better colour gradience, resolution and refresh rate means a greater variety of books, games and media. We'll see what happens as app development actually starts and matures as future Kindle iterations come out. Kindle's future success is tied to E-ink's viability in cost versus quality and right now, one could only guess beyond reading and reference-type apps. I think E-Ink is exciting in the sense of how little power it consumes in static display. The Kindle 3 supposedly lasts up to a month if the wireless radio is turned off. Lowering e-ink cost regardless of the quality combined with a few solar panels here+there, and the technology's use cases in advertising, retail, consumer, and corporate stuff etc go up drastically.
