> But does every networked device have ethernet these days? My laptop doesn't, nor does my phone.
Every stationary or semi-stationary networked device should probably have Ethernet. A desktop or laptop should; a phone shouldn't (because it's mobile). It'd be nice if IoT thermostats and the like were wired, but that would require homes to have Ethernet-over-power or Ethernet runs in the walls or something.
WiFi is inferior to Ethernet, except when mobility is necessary. So for mobile devices like phones, it's not needed. For tablets, probably not (but imagine if your charging cable could also carry fast, reliable networking to your tablet, so you could have a better experience while reading or watching TV, but still be able to get up & go).
