Bob, I haven't heard any serious talk about e-paper displacing the screens in notebooks, on desktops, and in home theaters. Keep in mind, the LC and plasma-based incumbents have at least an order of magnitude faster response time, can be brighter than light impinging on its front surface (rather than less bright than white wall paint), and have much better color saturation and luminance.
After e-readers and signage, e-paper will probably do well to combine with a digitizer to make an electronic drawing board. Putting a resistive touch screen, which can cut 10% to 30% of the light each way, in front of e-paper would be unappealing.
