No one in their right mind is going to use ATT's International 3G plan. You are going to go buy a prepaid data SIM when you arrive at whatever country. Now wouldn't it be cool if every single one of Apple's data partners plans could be accessed directly from the iPad as easily as ATTs? Go to London, stop by an O2 or Apple store, pick up a microSIM, pop it in your iPad, pick your plan from your iPad, and good to go. Your CC is billed for the plan so no worries. Move on to France, same deal, etc, etc. Even better... you could pick up foreign SIMs in the US at any Apple Store so you didn't even need to track one down when you arrived. If life were so uncomplicated like that.
