Looks interesting. It will be awhile until I upgrade to a phone supporting wireless charging though. I'd guess such a cradle would have to be wired to be off with ignition off or to a switch.Now they are designing something we can use.
I have something like that for my car vent. I wouldn't trust the clamping mechanism without a carpeted floor beneath it to catch the phone if it drops.
And the stories of smartphone cameras failing from the smartphone being exposed to handlebar vibrations, would keep me from even considering it in the first place.
