Hi,Because of the confusing naming practice at Shanzhai tablet market, and almost always wrong device picture/specification combination by eBay sellers, I try to collect available information from popular android tablets at this moment.If you are expert for this subject, please take a look at on the attached specification table, and point out any incorrect/missing info. I hope after a few round we will have a comprehensive material.If you are beginner who plan to buy an android tablet, I hope this info sheet will help you to distinguish the devices, and find REAL specification for them.(And if you are site admin and think this is a good initiative, please help me keeping this message visible)I will update datasheet regularly...Thank you for helpView datasheet...
