Someone explain to me why wireless charging matters

People are acting like they can walk around their houses with their phone and it'll keep charging with this technology, but the stuff Nokia showed required you to place the phone on a charging "pillow." How the hell is that any different from connecting it to a cable? It's the same principle--your phone is locked to a position, and if anything having a charging "pillow" or dock is just more wasted space on your desk.

I swear Nokia and Samsung could make their phones with a giant toilet paper dispenser attached to them and people would claim the iPhone was falling behind by not including it.
