In the current issues of aviation magazines, there are ads for eFlyBook. This device contains various flight documents for power pilots, but the interesting part is the use of a "digital paper" display. Other than retail store signs, this is the first commercial use of digital paper that I have seen. Digital paper is a technology that uses tiny rotating beads, black on one side and white on the other, electrostatically rotated, forming a non-volatile, non-luminous display. The upside is that it is clearly visible in full sunlight! The downside is that right now DP is limited to monochrome. I am hoping that the PDA makers will someday produce a DP-based unit, which might eventually be useful with SeeYouMobile, WinPilot and the like. It's really hard to see the display on my HP IPAQ in the cockpit, even though the one I selected was recommended as one of the most visible. I did some searching and did not find any hints of such a product yet.
