Tim, your LAX trip 5 years ago on Qantas would undoubtedly mean it was on a 747...
Now; Qantas A380 Business - improved fully-flat Skybed with incredibly better/more reliable IFE, much more pleasant cabin environment/design with reduced noise level, and cabin crew who haven't been 'around the traps' for 30 years and who actually enjoy their job (and if some have been around for 30 years, A380-land forces them to have a change of attitude - in most cases)... Worth trying again, if you have the chance.
