What ever happened to the stable platter?

I always liked Pioneer's Stable Platter. Why does it seem like it is passe?
The fact that Pioneer has discontinued production of this mechanism may have put a BIG damper on things. Sean
It was deemed unstable :^(
I have 2 machines using this platter; very nice, I always liked them too. Whatever did they replace it with?
Doesn't Wadia use the stable platter?
I don't know if Wadia did, but i know that Theta did on the Pearl and Miles. Sean
