I don't use Apple products, but I do use a wireless charger for my Samsung phone. The reason is that I keep it in a rather beefy protector case and fiddling with the charging port flap is annoying, which would also impede it working with any kind of dock, and I'm not about to carry a naked phone - I can't trust myself not to drop it.
The one distinct advantage of wireless charging is that my Galaxy S5 has the same waterproofing flap over the USB port, and I've already worn through one of these (thankfully Samsung had the foresight to make them very easy to replace when the clip breaks), so the charger does not require opening the flap.
