I think a big factor if you feel like you need wireless charging is the device battery life itself. I get 6.5 - 7 hours screen on time consistently. That lasts me from 6:30am - 11pm. So keeping my phone topped off all the time serves me little to no purpose if the phone can already last me all day.Sure, wireless charging isn't necessary. Neither are power windows in a car. I mean whenever you need air you can just lean over a little and roll the passenger-side window down. But after having power windows in my last few vehicles it sure is nice to have.
It's the same with my S8. My wireless charger quit working a few weeks ago and I haven't picked up another one yet. The phone does charge a lot faster hooked up to the wall, but the convenience of keeping the phone topped off while sitting at my desk was convenient. Now I find myself only charging when the battery is close to dead and now I walk around with less of a charge than before.
I've owned 3 phones with wireless charging and only used it once on my first phone with the feature (nexus 5) and that was just to test it.
