I hope you’re right, as it would be better to have only one model, since the support of Teclast (“Tai Power” ;)) isn’t too good, and there are a lot of derivations with (almost) the same HW, but one of them is single OS, one of them is dual OS, one of them has a 3G modem built-in… Teclast would be able to support A6C9 properly (this, because I have this x)), but not all of them simultaneously.
