content: why the fuck is there an ethernet adapter instead of onboard wifi?  Because of power over ethernet, which is how most of these are used. Believe it or not, the majority of purchasers of small computer like this aren't tinkerers like us, but big businesses  23c  /factories/etc who uses them for automation. You string the ethernet cable out to your sensor location (the cable of which you already needed for data) and the computer runs off of the power supplied on the cable.  Kinda defeats the purpose of a small computer that can be placed anywhere  It is literally what enables small computers that can be placed anywhere.
