The heat isnt an issue if you
A) use an external usb mouse/keyboard.
B) Prop the laptop up on a bench so there is plenty of ventilation underneath...
It is true, these puppies to run very hot but its the nature of the beast... just look after it and do the right things and it will run like a dream (like mine does
As for AW service in Australia, All of us here had some pretty miserable communications issues when we ordered them. Take your ETA date and add a month and thats around the time you will get it.... A famous quote from this thread is "Patience, Patience, Patience" (thanks Shazza)... But its not that bad... if your prepared to wait.. and be patient this system will knock your socks off!
As far as the customer service goes after you have received your AW it seems to be excellent in Australia. Of the few guys who have had issues on these forums most of them have had the issues resolved quickly and professionally.
I hope this helps mate.
