In the following video Charbax shows off a 7" tablet with basically the same specs as the one I posted earlier. The maon difference is that instead of the Boxchip A10 chip, this tablet has the A13 chip. It has the same CPU and GPU, but Boxchip managed to shave the cost down by leaving out components like HDMI-out.
Its not clear what else they left out of the tablet, so there's a chance that BoxChip might even be able to get the price even lower.
Like the other tablet I showed you, Charbax is trying to organize group buy via his website. If he can find enough interested buyers, he'll mastermind a deal with the manufacturer.
