Something I have noticed at tradeshows in the past:
People prefer to work collaboratively through kiosk content. The sales expert and client both benefit from a shared experience in navigation. The expert can drive the application confidently, much like a good performer with her favorite, say, viola, while the customer benefits from the queued interaction, the multimedia mixed with a personal experience, and the opporunity to explore sub-areas of the interactive. Used here in a luxury environment to sell something that is certainly not a necessity, but really, really nice. In this niche, the purchasing experience is very much a part of the overall product image and ownership experience, not just a compare and select excercise.
