The simple question is: do we really need wireless charging? what are the devices that we need to charge wirelessly? at least i haven't seen the urgent need for it yet.

I'm don't know of any credible evidence that cell phone radiation causes any harm. If you know of any studies that have passed credible peer review that do show a link, I'd love to know. As for Inductive charging though, remember that EM fields fall off at 1/r^2 (pretty fast), whereas magnetic fields fall off at roughly 1/r^3 (super fast). That's why refrigerator magnets hardly do anything once you get them 1-2 mm away from the fridge. As further evidence for the lack of danger are MRI machines. There, you're sitting in the middle of one of the strongest magnetic fields on the planet, and again, nobody seems to be harmed by them (except by the stray piece of iron that flys into the machine) Of course, we need to keep vigilant for dangers, but a few charging pads around the house hardly seem like they'd pose a threat to anything, especially if they are only on when they sense a unit to charge.

cell/smart phones, laptops/tablets, MP3 players... Yes a winner Everyone hates lugging and plugging in chargers. All others like TV's... why? A universal one that my cell phone, laptop or whatever can be thrown on to a desktop/dashboard... and get recharded will be a winner. I do not want 17 different inductive chargers all over my house, office and car. This would not be much better, only saves the hassle of plugging in

Wireless charging is always been an interesting topic. However whenever I hear about wireless charging I got worried about its impact on human. There is already a known impact high energy cellphone signal impact on human body. The energy out of cell phone is much smaller than wireless charging energy we are talking about.
