Hey Jeff,
I know that Archstone uses kiosks in their leasing offices.
The one thing you really need to look at is how scalable arese the kiosks for the future. The kiosk might have all the "bells and whistles" installed currently -- but as technology and needs change, can the kiosk be updated easily and without additional cost. From what I have heard, this is tough.
BTW I have a great solution instead of the kiosk -- Interactive Digital Display signs. Think about those boards you see in hotels, conference centers, etc. that you can touch for further information on the location including floor plans, maps, weather, nearby dining establishments, traffic, etc. A good example is the "Go Boards" in Marriott Courtyards. These are completely scalable, feature drag and drop technology and can host a myriad of information from current availability of units, current pricing, events schedule, local dining and shopping establishments, schools, etc. Also these boards can be updated "on the fly" by anyone (with the correct authorization) from a browser with drop and drag technology. You want to see this product before making any decisions regarding kiosks.
If you or anyone else is interested in learning more, send me a note.
Best regards,
Leigh
