Builtin wifi capability, even if via a USB dongle is something I would like to see in most devices. Not having an ethernet cable attached removes a possible ground loop and attractive path for surges during thunderstorms, and etc.
And yes, I know about single point grounding and can use a common point grounded local lab network switch. Wifi would still be better in this respect. I actually have an entire rack of gear on a common rack switch that I then have linked to the network via fiber just for these reasons.
