Qi is that standard. Built in to lots of Androids now.
Only real issue with it is slow rate of charging. Not a problem for overnight recharges - but my phone still discharges when I'm using GPS + Bluetooth in my car's Qi holder.
Unless you're at Starbucks, who have deployed Powermat/PMA. Even though Qi has vastly more support from phones and chargers (Toyota is even putting Qi in some cars), there's probably many more people who have actually used Powermat, just because of SBUX.
Type C USB would be nice. On the other hand, I don't have any type C USB connectors / sockets in my possession yet.
I'd really like a wireless recharging standard. Just toss your devices onto a surface and they charge overnight, it doesn't need to be fast.
