Android runs on it, but (as noted in the review) Eken (and the other OEMs) haven't released any sources, so as yet there's real way to build other kernels that will boot, or support the built-in peripherals in the SoC.

I saw the video review you're talking about, I think. Maybe my expectations were just too high, or alternatively too low cos I really did buy it expecting to just pull out the main board and use that...
