Finally an answer to the battery-question:
"Dear Mr. Rohde,
The iLiad only uses power when a page is updated, the 10000 page turns is based on the available battery charge divided by the amount of energy needed for a display update. A more realistic model is that users download (wireless/wired) ones a day available content (like a newspaper) and read for 3 hours per day on the device in which case the battery needs to be recharged every week. If more frequent connections are made or the device is used interactively (e.g. writing on the device) the battery life is of course reduced"
That is good enough for me...now if they manage to finalize their pricing and make it a bit moe affordable...then I'll get one right away...
