Palm Pre beat them all years ago. I dont understand why it has taken so long for everyone else to offer it.
Because until wireless charging actually is widely available, you can't just use a cable to charge your phone - you need an expensive cable with extra electronics to do so. Rather pointless, unless you want to go completely sealed for a water proof device. Until this happens, support for it in phones is a pointless gimmick. Ikea's move is one of the best things I've heard for the future of wireless charging.
