I'm getting a new car and one of the add-ons is wireless phone charging. For it to work, I would need a Qi case for my iPhone 6. So I guess I have the following question: Is Qi charging a technology of the future or past? I ask because I will be upgrading to a new iPhone when it comes out (not the $1000 one though). I don't want to get this for my car but find out that the technology is irrelevant with the new iPhones.
