E-ink on high street shelves

When I first read the E-ink case study for business school I assumed it was fictional, so cool was the technology described. However it wasn't, it was real and now you can buy the world's first electronic book using E-ink technology. The resolutions still a little less than great, the price a little high, but that's not the point. Once Moore's law kicks in these things will become standard.

School textbooks on subscription would be a great market for these. For a one time purchase of a display (insured) and a lifetime subscription you can access all the textbooks you need for fourteen years of your life - with an extend to university option.
