I saw a TV ad yesterday in which Telecom are promoting broadband at dial-up prices - ie. $16.95/month. It is a limited time offer, and the cheap price applies for only the first 6 months, but even so it sets an interesting new benchmark for entry-level broadband.
It looks like the $16.95/month price applies only to the essentially useless 200 MB/month plan. However, they also mention $13/month off any other plan as a starter.
