You make good points.
Here's why I want Apple to adopt wireless charging.
Some cars makers are now including wireless charging in the in-car storage places you would put your mobile, benefits self explanatory.
I know someone will disagree but when Apple adopts a technology the rest of the industry copies or tries to out do it; I genuinely believe that if Apple did not have their quest for thin and sexy devices, the whole industry would not be as mobile as it is today.
What heck has that got to do with wireless charging? Macrumours posted a Apple patent for wireless charging which look at charging multiple devices at a single time without the need for the device to be on a plate, let's say it beamed it across somehow, that's kind of innovation we will get if Apple adopts it but for now, we have to start somewhere.
MagSafe is good and i liked it on my 2011MBP but it is time to move on from wires, i'm no environmentalist but i can only imagine a wire free future will be good all around.
Hmm.. Even more electromagnetic fields flying around - not sure that's great for the environment overall!
As I said there is a UK company http://witricity.com - that is at the forefront of this. It's a great idea for lots of reason so long as it works well and for the most part Apple waits until things work properly before introducing them.
Wireless charging and better data transfer would probably come hand in hand.
The problem is of course that all these companies are producing their own methods and they are not compatible and that's the problem with cars etc. they buld a car with as LITTLE upgradability as possible with regards to the electronics etc. Certainly cars like Tesla - they have actually stated that the Autopilot wont get physical upgrades - so you just have to buy the newer model... They are the smartphone of the car industry ( still want one though! )
