Thanks Capri. That would be the best workaround for those people living in places where ubiquitous fast internet connection with unlimited upload/download quota is available. In my country, "unlimited" monthly cellular connection packages are available, but still with effective limited quota up to 6GB. Meanwhile, free fast wifi connections are still scarce. Therefore, dropbox option may not be feasible option for me ... yet. If only we can attach external storage device via cable to our iPad ...
Well you have that right! my #1 wish for the iPad is some sort of external storage capability. But then then Apple could not get away with charging so much more for their 64 and now 128 gb units.
