Mine only came with 3 stands, so maybe the package has changed within the last 3 months or so.
A "clip on" mount (shown in most of the publicity photos) designed for mounting onto the top of a powerbook or ibook and held in place with a thumb screw.
A "desk stand" with a flat surface that you can stand on your table or desk in front of your monitor, possibly aimed at emac users. Has an adhesive bottom to stick it in place if you want.
A "flat screen" stand, similar to the desk stand one, but with a vertical flat surface instead of a horizontal one, you are supposed to stick it onto the back of your imac, or cinema display, having the camera poking over the top at you.
It wouldn't suprise me if the kit has recently changed, as i dont see many people willing to permanently glue their isight onto their desks, or expensive 23" cinema displays, which seems to be how they are designed.
