That's cool! I've used enough raspberry pi's over the years to know that SD cards, even if industrial grade are likely to fail at some point so I try to avoid booting from them. eMMC would be much better but sometimes a pain to flash depending on the tooling available. Having a SATA port would allow to use HDDs which provide a lot of capacity for cheap. I guess the processor needs to be an Amlogic for the best media experience?
