I hate playing the Apple pricing game in the forums because we all want this stuff to cost less. I think the folks who say that Apple pricing logic suggests $1699 to $1999 are correct. Apple basically doubles what top of the line monitor mounts from Ergotron or Humanscale cost and that would get you into that range. This patent is very different in terms of the level of stability it appears to afford. It should be possible to use it on an adjustable standing desk, for example, which is something you wouldn't want to with most monitor arms since they'd go out of position every time you raised or lowered the desk. Definitely not for everyone.
