if you haven't bought an iPad yet the good news is that you now have more choice. Telus has started offering data plans for the 3G models, offering 500 MB of data usage per month for $20. if you manage to go beyond the monthly limit, the penalty is 5 cents per MB over, up to $30. So the worse you can be charged is $50 per month.
By comparison, Rogers offers a lower entry limit of 250 MB for $15/MB, which may be too little data to for some to feel safe with and a potentially lower price for the higher data plan at $35 for 5GB/month for heavy users. It's unlikely you'll ever go above 5GB.
