I don’t know about the other cases you mention but the AMADEUS terminals don’t seem very efficient. You ask the woman at the counter to change seats and mashes away at the keyboard for a good minute before she tells you there’s no seats sorry. But in any case, we’re really talking about ipads, 99% of users buy them precisely because of the friendly UI with its animations. Efficiency is the last thing on their mind.
