Hi Hmoll,
Independent fingers are VERY important to play many different types of music. In many works of Liszt -Eg. Grand Galop Chromatique, Soirees de Vienne No.6- you need to hold down chords while playing melodies and grace notes-ALL WITH THE SAME HAND!! Yo need independent fingers to do this.
And as for your comment about not using independent finger technique after the classical era, that's also nonsense. In Prokofiev's march From the Love for 3 Oranges, to play it properly, notes must be held down with the thumb while the melody plays with all the other fingers. You will not succeed in performing many different types of work without independent fingers. Of course- hand weight, inertia, momentum, al the other techniques have value too. However, never say there is no use for the independent fingers and quiet hand technique.

Who said you don't need independent fingers?
What I am saying is the type of technique where you keep the wrist still, like that apparatus described seems to be disigned for - and utilize finger independence almost exclusively is a technique that has been refuted.
It's blindingly obvious that finger independence is important. However, a contraption that keeps your wrist in stationary seems like a formula for injury, as is complete finger independence at the expense of wrist, forearm, upper arm, shoulder.
Yes, I understand the concept of different fingers playing different notes, voices, ornaments... I do play the piano, after all. You won't get through page one of the Love of 3 Oranges march, "Grand Galop," or any other difficult piece using fingers alone. I think you already know that.
