This is more than twice the price of the Musebook (using a SpaceMIT M1 8-core SoC and also a PCIe slot for an SSD), which has unfortunately not been available for several months now...

Nevertheless, I got lucky and was able to order one last year. It's a nice device, but software support outside of the provided Bianbu Linux (a Chinese Ubuntu derivative) is nonexistent and the future of the SpacemiT SoCs is not exactly clear. I can run Ubuntu for the BananaPi F3 (same SoC) from an SD card with working drivers and power management but did not yet succeed in installing Ubuntu on an internal PCIe/NVME SSD I added.
