I used to feel the same way about Wireless charging, however ever since I have been using it on my Note 7 I really do find it very useful.Wireless charging where you put the phone on a mat, rather than on a dock.... don't really see the benefit.
But if wireless charging can work where you have a few things plugged in around the house so that the phone isn't losing its charge while you're using it, without it needing to be placed somewhere.... potentially brilliant.
I have a wireless charger for the car and for home and hard to explain really but it just adds so a lot to the user experience.
The car charger is my favorite, it prompted me to install Bluetooth to the van and now it is a cable free (I have the power cable for the dock very well hidden) and very elegant looking.
Its funny because I had been very upset at Apple for dumping the headphone jack, but I have ended up not using it in my vehicle after all.
