The Witstech A81 is pretty versatile, as you can clearly see from this video that shows it double up as an e-book reader to keep up with the times. While nowhere near as interesting as the iPad’s video demonstration, it just shows that the iPad will have some challengers in this niche gadget market, although whether they will offer serious competition is another question to answer altogether. The A81 runs off Windows CE, and will feature a 7″ touchscreen display, portable media player capability, e-book reader support, Wi-Fi and Bluetooth connectivity and 16GB of internal memory to get you started, where everything is held together by a Cortex A8 processor. It will retail for less than $250, targeting Chinese-language oriented users with the latest version of QQ pre-loaded.
