iPace has a working internet browser. I asked a Melbourne product specialist during a test drive last year why it wasn't available and she just said that it wasn't legal in Australia.Possibly due to the fact that any internet browser does need an input from someone to 'browse'. Under, at least, NSW law this is illegal. The only time you are able to touch an internet enabled device is to immediately pass it to your passenger. Nothing more. Bluetooth enabled phone is fine... you are not touching it.
I can quote the legislation but it is not hard to find. The more interesting point is how fuzzy this has been become as technology outpaces legislation by orders of magnitude.
