Wireless charging remains one of the most frustrating technologies around, because while it's here, it works and it feels like living in the future, it isn't as widely supported as we'd like.

It's rather like Google Wallet's NFC payments in that respect: the idea's sound but maybe it needs a fruit-themed firm from Cupertino to get on board before it'll really take off. An iPhone 6S or iPhone 7 with wireless charging would be great, especially if the same charger worked for next year's Apple Watch too.
