There are two model telechips 8901 and 8902, 8902 is dual one core for apps one core for dsp. The telechip would prob be better for video and 3d gaming, I do not know if the telechip brands have an accelerometer inside. I plan on doing another video within the next hour or so demonstrating wifi and a few other apps and how well the accelerometer works.There are sellers on Aliexpress now offering the zt180 for 180bucks US including shipping I have no idea how reliable some of them are but if you find a reliable source for that price your getting a good deal. I managed to get mine for 193(213 - 20 Aliexpress coupon) After playing around with it for a day or so I cannot complain. The only issue I could see thats if it were a more expense item is that the quality of the lcd does not hold a candle to the ipad.
