Re: Ports
You can plug your headset into the little port with the picture of the headset near it, or spring for a bluetooth one. You do not need a tablet if you have this. It is basically a tablet replacement. What kind of tablet do you have that has USB ports by the way?
Also, if you can really buy one for AU$1300 you are getting a great deal. In my country it cost US$1300 which is AUD1600.
