I've given them a short visit and talked a little with their CEO. Unfortunately he didn't allow me to take pictures...

He basically confirmed things already leaking out:
- 6 inch screen, e-Ink (of course)
- ePub and PDF (both with and without DRM). I didn't ask for other formats, but IIRC the home screen also listed files in other formats
- Touchscreen (one you can use with your fingers. Looks like the same one from the PRS-700. Screen contrast is suffering a little...)
- Built-in 3G connection. WiFi is only available over an addon SD card (which will also be supported by the BeBook 1 anytime soon)
- They're currently developing an OTA bookstore for the device. You will be able to shop for DRMed ePub books over 3G connection. (They won't integrate with other bookstores like Lexcycle does but are negotiating with publishers directly)
- Built-in web browser
- RSS support
I've also asked them about some possible integration with Feedbooks ("the French guys" as he called them

), but it looks like they're not planning anything on that. You could of course use the browser and download Feedbooks.com content from there.
