Far-fetched: Do you think Monochrome E-ink screens will bring back simple PDA's?

[Not_A_Crook]

To simplify why I asked this question, I assume since the Jitterbug cellphones capitalizes on "Simplistic" functionality that adds usability to the older businessman/woman, will the black and grey EPD's mark a return of retro-palm-esque devices? Aimed at a younger crowd to be exact? I believe they COULD when they are around $80 to produce.

Also, remember those old and really small handeld flip-screen devices that look similar to netbooks? But was more of a super-smart calculator? Thats what E-ink could possibly return in favor to college use.
