I'm guessing that there are more wifi models being sold than cellular, but I wonder what the ratio is between wifi iPads compared to the cellular edition. For me, I was able to capitalize on a free unlimited data line that I had being a T-Mobile customer. I got the data line back during their Black Friday sales. I have been able to transfer the unlimited tablet line to the new 10.5" device in Space Grey. I also have a Verizon SIM in my iPad for emergencies. The service I have there is simply 1 GB for $10 a month on a postpaid cycle. I know that the extra $130 can be a significant turnoff to those that were thinking about getting a cellular model. My question is which model of iPad do you have and why? Also, maybe you might be interested in sharing your service plan with us for your iPad. If this type of thread has been generated before, please forgive me. I figured it would be interesting to see everyone's take on why they have what they have. Also, my iPad is my main device. I do have a Mac but it is more an iDevice server for my family's stuff.
