One of the best computer kiosks I have seen are the ones that they have put in at the airport. These kiosks are used to check you in, and prevent you from having to wait in line for hours just to get 5 minutes of face time with an airport employee.
At the kiosk you can scan your own passport, choose your seats, print boarding passes and even prepare your baggage for check in.
I really love these new computer kiosks for making my trips to the airport less painful and stressful. I recommend them to anyone traveling. If you are not sure if your airline offers these kiosks, you should call and ask.
