My main issue is with Printing.
I have occasionally used them to print Boarding passes, hotel details etc.. last minute presentations to markup on a flight.
I understand that the Qantas printers have support for Apple AirPrint, but what about support for users of Android phones/tablets (Google Cloud Print would be a possible solution) or PC laptops. I note I havent looked at this recently so don't know if this has been addressed or not.
I recall in the AA lounges for a number of years they have had a Print via Email function where you can send a PDF to a dedicated email and it prints.
