The EE Times have just posted an analysis of theBenQ K60, the first ereader with a Sipix screen. The article confirms a number of details we already knew (Wifi b\g, capacitive touchscreen, microSDHC card slot), but they also pointed out a couple details that I didn't know.
First, AUO made the screen controller chip. I expected this, actually; AUO own Sipix and BenQ.
The other interesting detail is that they estimate the hardware cost to be less than $100. It's not quite cheap enough to compete in the US market, but should a price war happen in Europe the K60 should be able to survive.
