Right now, I wish I was living in Tasmania. iiNet has just announced that their 1TB plans announced this week are available to their NBN customers, with the added bonus of 100Mbps speeds until June 2011. And for the same price as everyone else pays for ADSL2+ speeds, no less!
These updated quota plans will be available from September 1. And while the time limit of 100Mbps speeds until June next year sucks (the price will probably go up then, I guess), having high quota, high bandwidth internet access would essentially mean you could use the net as an IPTV portal without ever having to worry about exceeding your data allowance.
