re: Wireless Device Chargers: Right Idea, Wrong Price
There are a lot of different implementations in the Qi specification, and there are many solutions that offer spatial freedom (such as the Nokia charging pad). I don't think you quite understand the freedom that is available for manufacturers to implement solutions under the Qi standard.
In terms of cost, there have been several reports that Samsung backed out of a A4WP solution and opted for a Qi solution because A4WP was too expensive.
I think at the end of the day, this technology needs to be cheap enough to build directly into phones. I think you're seeing the cost point of Qi come down as the technology is built into devices such as HTC DNA, HTC 8X, Nokia Lumina 920, Nexus 4, etc... Then a charging accessory that will continue to be compatible for years to come will not seem so expensive.
