I found an interesting rumor over on Akihabara News. They have what appears to be an ad from Cube, a Chinese tech company. The ad is in (I beleive) Chinese, so I'm going to have take their word for what it says.
Except from this cute little babe, there is very few information on this upcoming product, however, they announced that pretty soon they would propose a 6” e-Book with a capacitive touch screen (color), running Windows Mobile 6.5 and Wi-Fi.
Now the other peace of information revealed here as well is the price of 999RMB (a bit less than 150 USD)… So wait & see.
