CotytechExpandable Apple Desk Mount Spring Arm Clamp Base - Silver

I purchased this mount a few months ago not realizing it won't work with the new 27" iMac. Is there an adapter so I can use it with a non-apple displa

Where can you get a longer pole and an additional mount for two 27" cinema displays?

Is there a position where my 27 inched Cinema Display will lay flat on the desk (face down)?

Does the spring make noise when moving the arm? I want to use this in a recording studio.
