That is currently a promotion, due to expire on the 31st of December this year. Once it expires some public 'suggestions' have been that it would deduct usage from your monthly allowance.
Which makes sense to me. :)
Cafe net also have all day passes which gives you unlimited usage for a 24 hour period. Remember that mobile data (cdma 1x/evdo and gprs/wcdma/hspda) are all expensive once you hit the plan limit. $0.50+ a mb is not exactly cheap. While the cafe net options are prepaid and thus the worse you can do is burn up your allowance.
I never once claimed that mobile data charges make sense. I just couldn't believe that CafeNet was even more insane.
I fail to see how this comes into it. Corporate users probably wouldn't be streaming youtube and music from home...
No, they wouldn't. But then again, they wouldn't require traffic to be delivered internationally, which is reportedly the dominant reason for the current price of broadband. So, if the dominant traffic flow is national, I would expect the traffic to be cheaper than the current wholesale international traffic cost.
When you can span those plans over multiple months (who knows how long they last - a year?), then it does bring things into the picture. Remember you still pay for those plans even if you don't use them. Alternatively comparing them to roaming rates (Vodafones infamous $30 a mb comes to mind), it can be quite a competitive rate for some.
The prices I quoted were without commitment. They are cheaper on a 2yr plan. Yes, I agree, as I stated in my last paragraph, it is pretty cheap compared to roaming rates (AUS seems to be 10/mb). Which indicates who CafeNet's market is - people who don't live in NZ.
