In addition to pictures, I prefer to take a video camera and go on a "tour" of your facility with the walls open.
I also prefer hardline ethernet, because in a crowded neighborhood wireless throughput is not consistent at certain hours during the evening during "prime time". You can use tools like inSSIDer and bounce your channel around, but it's a little bit of a pain. I also have my own NAS for streaming movies and wireless does have bandwidth implications of the maximum quality of your movie rips without introducing jitter during playback (DVD quality rips usually stream fine, but Blu-ray rips can vary, animated usually do ok, but certain film types with a lot of noise do terribly).
It's also very frustrating if you're a gamer and you depend on a certain quality of latency. Maybe there's a way to improve that, but I've never been able to MOBA on Wireless without a certain amount of risk that my network connection will drop at the wrong time during a 20-30 minute game.
Different users have different preferences, so YMMV.
