Note: The information in this post was current as of January 2010. It might be out of date now.
Update: Charbax shot a hands on video of the PB901 at Computex in June 2010. Surprisingly, they haven't changed the design much (but they are quoting a lower price):
Pocketbook had a prototype 9.7" ebook reader with the new flexible screen in its booth at CES. You might not be able to see it in the photos, but when I held it in my hands I could see the screen wasn't flat. There was a slight bulge behind the screen from one of the circuit boards.
I asked, and I was told that there will be 2 models. The basic model (PB901) is projected to cost around $450 and be available in September. The PB902 will have Wifi and a touchscreen, and will be available later. Note that the one in the photos is not the production model. It's a prototype that was thrown together quickly in time for a demo for the Russian Education Minister.
BTW, this isn't the first mention of the Pocketbook 901. There was a couple pictures posted in MobileRead's Deutsches Forum. But I do believe these are the first shots in the wild.
