It occurred to me that this particular device is the epitome of the ereader market in 2009. A company decided to go outside their usual market and started developing an ereader. A little info is leaked to the press and everyone gets really excited. Nothing is officially announced, but the media get into a frenzy anyway.
Now that was 2009, you have to admit.
Unfortunately, the Mediabook was never released (or even announced). You can't really say it was cancelled; it never really existed. But I think we ever saw it because of either the iPad launch and the Nook/Kindle price war. Either event changed the market enough that the Creative Zii Mediabook never made it out of the lab. Which means the Creative Zii Mediabook is also the epitome of the ereader market in 2010.
Interesting, isn't it?
TBH, I don't think the Mediabook died completely. I think the current Zii tablets (7" and 10") are probably based on a lot of the same work as the Mediabook. I think they're too similar to be a coincidence.
