I wonder why we still use the same old E-ink technology on the market right now. There are a number of other technologies (Mirasol, Liquavista, and more) which are better in terms of contrast, refresh rates and all. It could be all linked to pricing: if nobody is ready to pay for a e-reader costing more than xxx dollars, maybe we will be stuck with E-ink for a long time. It may be "Ok" for some people, but for me e-ink has a far too low resolution to be attractive enough to replace paper.
