I was about to comment something about how this thing seems nice and circumvents the problem with repurposing powerful old phones which is that you are limited by the I/O which is often usb 2.0... If it has 100mbps ethernet I don't really see much benefit over a usb c dock/hub with ethernet or something. I'm pretty sure if you connect a gigabit ethernet adapter over usb 2 you can actually get higher speeds.
