I was able to have a look at the new
PocketBook 903 eReader with 9'7 eInk Display at
the IFA in Berlin last week. That one (comes with a wacom screen and stylus too) handles landscape quite nicely.
Wasn't able to test annotations though. They are still working on the firmware (the reader as such and TTS worked very well already).
As it has no second (colour) screen it's a different class of device, but it's nice to see other bigger devices apart from the eDGe, the Kindle DX and the old iRex.
Pricing for Europe for the 903 will be published at the Frankfurt Bookfair in October.
