How do you know that wireless charging isn't quite ready for primetime yet? When you need to plug something into your gadget in order to get it to charge "wirelessly."
The WildCharge PowerDisc plugs into a gadget that doesn't have a WildCharge "skin" available for it and lets it charge without plugging it into the wall. But it seems to make charging less convenient than the traditional method. I mean, you can either have a cable on your desk that you plug your Kindle into to charge, or you can have a big flat surface and then a dongle that you need to find whenever you charge it.
Until this is built into gadgets, like the Pre, I can't imagine spending the money on it. [WildCharge via SlashGear]
