moxpearl:sbiddle: Why are oranges and apples not the same price? They are both fruit.
That does not really help, neither do the rest of the comments
I am asking how can they justify the extra $1481 dollars..
Not just "Because"
The thing is if you're going to experiment with higher caps, it's much easier to do it on a more limited customer base. If they allowed 1tb on adsl they'd get a whole lot of extremely high usage customers. But with UFB they're already cutting down who is eligible. I'm expecting a lot of users will only do 200gb, or thereabouts. And if it doesn't work out well they can always change the pricing down the track.
Also bandwidth prices are coming down. And it's many years away before UFB will really have significant availability.
Anyway, if push comes to shove, and you really want to do 1TB/month prepaid on ADSL, I'm sure you'll find Orcon or someone else could do you a deal for $200/month or thereabouts. There'd probably be a few caveats though. Like you'd have to be on EUBA, if Telecom start enforcing dimensioning then could be withdrawn etc.
