Optus leading the way in terms on Mobile Broadband data.
50GB+50GB = 100GB total for $70 a month with no lock in contract.
Month to month or can be contracted on a 24month deal with a modem.
Edit: I just bought one this afternoon. I can confirm it comes with TV and Music streaming free.
I'm close to ditching my ADSL for this type of offering.

Description of the service
This is a Postpaid Mobile Broadband Service which includes
a Data Allowance of 100GB for use within Australia. In times
where our network is busy, data usage on this plan will be
prioritised at a lower level than other data on our network. This
means that during busy times you will experience slower speeds.
That is a great deal. I couldn't figure this out easily from reading the site but can you get multiple sim cards to use in multiple devices (eg. a modem, a dual sim phone, an iPad, etc). It sounds like if you have multiple Optus personal plans then you could aggregate the data allowance?
