I don’t have the specs for the Bambook, but I do know that it has Wifi and that Shanda have launched an ebookstore to support it.
UPDATE: One of my sources have come through for me. I now know that the Bambook is using a 800MHz Marvel CPU, costs, 998 Yuan (during the beta at least). It also won’t be going on sale on the 9th. Instead, it will be in a closed beta.
I also found some unboxing photos.
