The C67ML is also on sale at
http://www.onyx-boox.ru/boox_c67ml_magellan2 - which lists the weight as 169g (as opposed to Onyx Boox's normal, very broad, "≤" weight ranges).
This model is currently pinned as my 'go to' model if the second page-forward button on my i62HD conks out before O-B releases a better 6". But I am hoping that the D67 (or better yet an O-B with the Kindle Voyage's screen technology) may eventuate before then.
Does anybody know why Carta screens have been so slow to become widespread? There are only a handful of models featuring them after a year, whereas HD Pearl screens became ubiquitous almost immediately. Are they that more expensive than Pearl that they've been sidestepped?
While replacement models that are lighter and narrower for the same screen size are welcome, I was rather hoping for an improvement in contrast and/or resolution with my next buy as well.
