Way overpriced compared to other alternatives like the Odroid Go Advance which costs less than 1/3, runs Linux, can emulate plenty of other gaming platforms, and by having a gpio connector exposed to the outside and thoroughly documented hardware seems a really interesting hacking platform. Also, it employs both a RockChip RK3326 and a ESP32 module.
