    with respect to RF....granted, you aren't holding the charger next to your head...but how "near" is near-field when it comes to putting power through the air and the ramifications around EMI and/or health.

    Call me a conservative engineer... I don't care.

    What's the point of this? Is it more efficient (using less electricity) than just plugging a cable into a small socket on the side of the phone? I doubt it.

    It easier to use than plugging in a cable in a socket? Hardly.

    Is the charger easier to replace than those standard nokia chargers that everyone has several of lying around? Doubt it.

    Will it be standardized? That'd be lovely. But normal chargers should have been standardized long ago.

    The only added value I see is that you can now completely waterproof a gadget.
    I can see the added value for things like electric toothbrushes - those must be encased in a water proof shell. But the whole point of phones is that you replace them every 1-2 years. Making them stronger and water proof is bad business.

    If you can charge something like a battery over the air with (i'm assuming) magnetic waves.. Is it somehow possible to have the same battery be drained by opposing magnetic waves or some other sort of interference while it is on or off the charger?

    What's the efficiency of these? The last thing the world needs right now is another way to waste energy.

    Still ... if it's expensive enough and leads to standardization it might mean less overall waste then having dozens of chargers for everything.

Make it right before you make it faster.
