There is nothing about inductive charging that makes it better than wired charging. That means you won't be able to pick up your phone while it's charging unless you pick up the charging dock/pad as well. I never will understand this.
If your argument is that it's much easier to just drop the phone on a pad rather than sticking the charger into the phone, give me a break. You're talking a second or two at most.
Well, much of this is a matter of opinion, however I'd like to mention a few benefits I would have.
First and formoset is wear on the cable and port. The port im not terribly worried about (for my own uses) but I have frayed many an apple cable just using it normally. I like to plug my phone in at my desk, pick it up, put it down, etc. This probably contributes to the frayed. Obviously I won't be plugging it in and out during the day. Laying it down on a pad would elminate that strain.
This leads me to the time savings. Sure it is only a second or two. I guess for me it is a matter of conveninece. I set it down and don't think about it. This also opens possibilities at airport terminals, coffee shops, etc. FWIW some of these already exist. No need for a cable when you can just set it down somewhere and get a charge.
Which leads my to my final point; car docks. My phone automatically gets placed in a car dock almost anywhere I drive. If I need power (longer trips) and/or don't want to drain the battery I manually plug it in. How convenient would it be to have a powered dock that requires no plug? Just slip it in and go. Everything else already happens over bluetooth so the plug is merely another cable that eventually gets trashed in the car. I have had the same dock for four years. I can't say that about the cables in the car.
I call these sorts of things "quality of life" improvements. It's not some killer feature that is going to overall change the way we use our phones. It's just a minor convenience. For example, second gen touch ID is much faster and more responsive than first gen. Was first gen bad an unusable> Absolutely not. But when I can choose, I will pick gen 2 all day every day (I know opinions differ on this too). The technology necessary inside of a phone to allow it to charge wirelessly is so thin, it's incredible. It's about the thicness of a piece of paper with the surface area of about a credit card. Honestly, the only thing barring current iphones from its utilization is the fact they are metal cases; perhaps Apple has something up their sleeve in those regards.
But the beauty of wireless charging as an option, is you'd still have the standard plug, if that is your preference, much like we have a choice to use touch ID, passwords, icloud locks, etc. All are optional, and if they don't fit your needs, you simply don't use them.
