LOL WhiteKnight I trip out of town regularly enough - I clock up about 1100k's a week in my car and I travel to work with dad 2-3 days a week
I also do a lot of remote and regional travelling as a keen camping and 4x4 enthusiast

I've even travelled a bit around your great state (though no way near as much as I would like to - I think I have a fair amount of "real world" experiance with these things.
NextG simply is garbage AT THIS STAGE.
I have NO doubt what so ever that NextG will be bloody awesome soon. But much like the whinging that went on when we switched from "analogue" to "CDMA" way back when because CDMA wasnt at the same standard of coverage (though it had the potential, which it soon realised, to be as good as and better than analogue).
But the fact of the matter is they are trying way way too hard to market mobile internet and bull sh!t wank to country and regional users who simply don't want / need that technology and simply want a good phone that can make and receive a phone call.
Look at the F156 its an AWESOME concept they have come a great distance with that phone. Places they went wrong - letting the contract to manufacture the phone (only available to Telstra) to a crap company like ZTE. You wouldnt drive a daewoo lanos up gibb river road - why the funk would you take an equivilant build quality phone up there?
An antenna for greater reception on poor coverage areas - a piss pore flimsy retractable unit? Why not use a decent SME or BNC type mount for a GOOD high gain antenna?
Mini-USB connection for the handsfree kit - are you fricking kidding me. You talking about a phone you want to give to truck drivers, grey nomads, bushies and tradies (probably the hardest people on a phone) and you want them to connect / disconnect it from a pissy little mini usb connection every time they enter / leave the vehicle.
Plus on top of that it has a confusing, slow menu and its basically a POS.
NextG (or any telecomunications infrastructure for that matter) should be government owned and telsra should be purely a retailer and NO telco should have exclusice access to any "network". This would increase take up of new technology and would keep prices down.
