Have a look at the English translation of the press release:
I attended the press conference this afternoon and I was quite impressed the speed of development of this epaper format. There are a number of research projects going on at the moment, aiming at future digital newspaper uses, but this commercial implementation really surprised us. It's good news for the iRex people, the iLiad will certainly get lots of attention the coming days.
The iLiad will be available in combination with a one-year subscription. Existing iLiad users can also buy just an electronic subscription. The newspaper is delivered using the Irex Delivery Service. The newspaper consists of a (non-drm'ed) pdf file, which is optimized for the iLiad's screen.
