Hey Quad .. yes .. it's wire free. But you have to do two things to make a powermat work efficiently.
Inside the powermat there is a Primary
Induction Coil.
So ...
1. There has to be a Secondary (or receiving) coil attached to, or inside the device that is going to be charged. The receiving coil is built specifically to receive the proper amount of electromagnetic energy from the powermat to produce the correct voltage for your device. (also add some tricky capacitors and a resistor or two to keep too much juice from flooding into your device.
2. In order to have efficient charging, the primary (in the mat) and the secondary (in your phone) induction coil must be magnetically aligned. If they are misaligned by even a few degrees, the potency of the incoming charge is decreased significantly.
So the reason I'm fairly certain there will be some sort of special case to snap onto the Droid is:
1. I've seen several pics of the insides of our Droids. I haven't seen anything that looks like an induction coil inside it.
2. We don't have any magnets inside our Droid to properly align the non-existent coil with the mat.
3. The powermat has more technology inside it than just a transformer. It also has an RFID reader that reads the RFID tag of the device that's sitting on top of the mat. That way it knows how to properly interupt the coil to create the proper magnetic field for the secondary coil that is sitting on top of it.
Those three reason above are why they are going to have to do something aftermarket to our Droids to make them work with their system.
I have also heard a lot of complaints from people that the powermat is dreadfully slow, even though they claim in their marketing to charge as fast, if not faster than your wired charger. Considering how fast my Droid charges on the USB cable attached to my PC ... I hardly ever charge it anywhere else.
Hope this info helped!
