Note that the plan you really want is the "Tablets and Gaming Devices". The "Computers, Netbooks, Aircards, Others" plan is a rip-off except for the $50/month 5GB plan, which is the same as the "Tablet" plan. On the "Computers" lower data rate plans, it is $15 per day, $30 per week. Data is data, so they are just ripping you off.
AT&T DataConnect Pass plans
* No Long-Term Contract
* Plans are active for 30 days or until depleted.
* Plans automatically renew every 30 days for domestic data plans, unless you cancel.
