2gb is ok if all your doing is email and light web browsing. If using streaming video like netflix you may just get by if you just use it once or twice. Also depends on how often your on wifi vs 3G. Currently I am on vacation and have been exclusively on 3G as finding open wifi points has been difficult. If you ordered the iPad before June 6, sign up for the 2gb plan and call at&t and ask them for the $30 a month unlimited plan. The 2gb really does limit your use of the iPad. The only downside to the new unlimited plan is that if you cancel anytime you cannot sign up for unlimited anymore, you'll have only the 2gb choice. If qualify for the $30 plan i would definitely sign up for it as its a small price to pay for always on Internet anywhere you go. And knowing that you can get unlimited data is priceless, you don't have to worry about if you are over monthly data limit.
