Fact is people have been argueing about whether or not to use them ever since they popped up in pianos. They start becoming controversial the moment they replace gravity and mass evidently. > The only difference I see between magnets and springs is that so far > the magnets are applied to the key and springs, to the wippen.

Which is a totally meaningless figure unless published along with the proceedures for measuring it so as to be able to confirm the validity of the claim.
