It seems like you are smart enough to complain like a little child. As clever as you are you could provide a solution for your as easy to setup and maintain devices. All devs have experimented with alternative arm boards. No one really likes them. If more speed is necessary it is already possible to use RetroPie with an Intel compute stick or NUC or any other PC. There is a gap between rpi3 and a PC which could be filled with one of these arm boards. But no one wants to spend time for arm boards with bad driver support.
