cokemaster: You're missing the point. I'm not saying its wrong to offer term contracts (even if there are / are not open terms versions), I'm saying its wrong to rail against them and then turn around and offer them anyway.
And I think you're missing the point of the original ad — at the time most (if not, all) postpaid plans from other providers had to be signed up with a 12, 24, or 36 month term. 2degrees changed that by offering all of their plans on a month to month term. Sure, they introduced term plans for those who wanted to get a free phone when signing up, but it was a game changer to offer all plans on zero term. The new XT plans all appear to be available on 0, 12, or 24 month terms but I can't remember if that was the case when XT first launched? And I bet Telecom have some business plans still lurking around that require terms. Same with Vodafone, lots of their business plans still require a term.
