Tell me there isn't collusion in the Canadian wireless world. I strongly encourage everyone who already has a data plan with one company, to get their iPad data from a different one. It's month-to-month with no contract, so there's no penalty or benefit other than just not giving another dime to a company you already pay for data from.
Having to pay for another data bucket when most people don't even come close to using up the one they already pay for is a complete joke.
