What real difference? You still need power - the phone still has to be in the correct location.

Not anything I am willing to spend a dime on.

YES, it is less efficient. Aren't we all just crazy about the highest possible efficiency and the least waste??? But, just ask a friend with a pacemaker to use one. The waste/stray field will include him or her. And be ready for medical intervention. If there ever was an invention that should never been introduced, this is. I figure, a massive class action suite will stop it. Until then blooming twits (er. marketing types) will keep pushing it.

Isn't the charging pad/dock/cradle connected to the wall-wart via wires?

Yep! but you get a loss in efficency due to the EM field having to induce a current into the phone.

Again its a marketing thing for people too lazy to plug something in.

One more vote on the efficiency issue. Until they design in a shape similar to an electric toothbrushes' toroid, I know jack...

What happened to 2 stainless strips on opposite sides, ala cordless phones? Is style sooo more important than convenience & efficiency?
