Well, I wish I didn't travel internationally so much after seeing the data rates both AT&T and Verizon are offering iPad users for monthly, non-contract plans. If you are deciding on whether to get a Verizon iPad or an AT&T one and will use 1 GB or less of data per month, Verizon just decided for you.
As you can see from the chart that AllThingsD assembled, Verizon offers substantially better 3G data rates for the iPad than AT&T does -- at least for those users who want to be on the lowest tier. For $15, AT&T will give you 250 MB of data per month, whereas for a mere $20, or just another five bucks, Verizon will give you 1 GB of data -- that's four times the amount from AT&T. If you want to keep it on the lowest tier, Verizon is the way to go.
