2 degrees offer 12gb valid for 6 months (= 2gb per month for $16.50) as a prepaid option, so easy to hide from the GF and not locked in for 2 years.
The $63.50 your saving a month would pretty quickly add up to the cost of your tablet, Im sure buying one at DSE on interest free would be around that cost.
63.50 x 13 months = $825 which would buy you the 3g ipad including the booking fee, then the savings you get vs rest of the 2 year telecom deal would be 63.5 x 11 months = $698 !!!!
This would only work of course in the broadband zone.
