Finally got to check out one of these this afternoon - deceptively easy to use, and somehow they got the seat preference wrong - easily changed.

Staff are in attendance to provide assistance, although I specifically said that I wanted to stumble through it - they seemed a bit miffed, but if I make all my mistakes the first time, I will remember them the next time.

Two machines located in the Qantas Club as well, but a lot of people seemed to prefer the reception desk - God only knows why.
