I've stated on other forums, that if you are going to only get <10 watts from wireless charging an Ipad, you might as well just use a solar panel.
You can get about 20% conversion efficiency from a monocrystalline panel, and you can actually optimize the frequencies of light that the panels absorb by using LED's that only emit that particular spectrum - giving a healthy boost there too. Make the light slightly brighter than the sun, and have it on a pad that only turns on based on "proximity" like some sort of magnetic on/off sheath, and you won't even see the light, because of course, its blocked when charging. Added bonus is that you can do trickle charge when leaving in regular sunlight on your desk upside down, or if you happen to have a glass desk - then trickle charging all the time.
I think the primary reason that Apple is pushing this induction charging, is because they do not own any solar panel patents.
I mean seriously, they had solar calculators when I was going to elementary school, and those panels were sucktacular efficiency.
BTW: The day that they said "glass backed phone" was the day I was sure that solar panel backed phones were coming.
