I looked around the web but couldn't find the data plan tiers and prices. I understand that you can use the Nexus 7 with AT&T and T-Mobile. On the iPad, the tiers are 200 MB for $15, 2 GB for $25 for AT&T. Are the prices the same for the Nexus 7? I'm thinking of getting the 32 GB with 3G for my mother - she doesn't have any internet access at all and it may be a good solution so that she can get started with email.
