Technology changes, and so should you. said on 12th January 2009
Palm's Pre must be using something similar to SplashPower's solution that could be built _into_ the target device (although they'd be foolish to use SplashPower's actual technology if they could develop their own as it would save on licensing fees).
I've read reports raving about this wireless charging and remain unconvinced. You're replacing lots of dedicated and small chargers with one mat that is large (even if they do make a foldable variant).
Also, the power supply to it has to be huge to charge all the devices on it at a decent rate and take into account the inherent inefficiency of wireless charging.
Did anyone mention how long it takes to charge devices from various power supplies with various loads on the mat?

@Technology - sadly not as they claimed they were not the manufacturers of the devices themselves. That seemed a cop out though so we'll just have to try and get one in the labs ;)
I also think your point is particularly relevant for laptops.

Surely you can just remove the battery?

Maybe is based in electromagnetic technology to be charges but i still remain faithfully to my usb for charging devices at home maybe could work this devices in airports bus stations parks and could be attached with magnets so u just place one in a walls, park seats or places where u can find wifi connections too ...

I think the casings are an ugly, but necessary, temporary solution to solve the chicken and egg problem. Once enough contact/proximity chargers of a given standard are in people's homes, device manufacturers will start to build the necessary circuitry into devices. But they won't start to do that until there is an established standard with a sufficient user-base to justify the additional manufacturing cost, so until then we're stuck with adaptor casings.
